hg: show the correct message when cloning an LFS repo with extension disabled

The `extensions._disabledpaths()` doesn't handle fetching help from `__index__`,
so it returns an empty dictionary of paths.  That means None is always returned
from `extensions.disabled_help()` when embedding resources inside the pyoxidizer
or py2exe binary, regardless of the arg or if is an external extension stored in
the filesystem.  And that means wrongly telling the user with an explicitly
disabled LFS extension that it will be enabled locally upon cloning from an LFS
remote.  That causes test-lfs-serve.t:295 to fail.

This effectively reverts most of the rest of 843418dc0b1b, while keeping the
help text change in place (which was specifically identified as a problem).

#require pygit2 no-windows

Setup:
  $ GIT_AUTHOR_NAME='test'; export GIT_AUTHOR_NAME
  > GIT_AUTHOR_EMAIL='[e-mail]'; export GIT_AUTHOR_EMAIL
  > GIT_AUTHOR_DATE="2007-01-01 00:00:00 +0000"; export GIT_AUTHOR_DATE
  > GIT_COMMITTER_NAME="$GIT_AUTHOR_NAME"; export GIT_COMMITTER_NAME
  > GIT_COMMITTER_EMAIL="$GIT_AUTHOR_EMAIL"; export GIT_COMMITTER_EMAIL
  > GIT_COMMITTER_DATE="$GIT_AUTHOR_DATE"; export GIT_COMMITTER_DATE
  > HGUSER="test <[e-mail]>"; export HGUSER
  > count=10
  > gitcommit() {
  >    GIT_AUTHOR_DATE="2007-01-01 00:00:$count +0000";
  >    GIT_COMMITTER_DATE="$GIT_AUTHOR_DATE"
  >    git commit "$@" >/dev/null 2>/dev/null || echo "git commit error"
  >    count=`expr $count + 1`
  >  }
  $ git config --global init.defaultBranch master


  $ hg version -v --config extensions.git= | grep '^[E ]'
  Enabled extensions:
    git  internal  (pygit2 *) (glob)

Test auto-loading extension works:
  $ mkdir nogit
  $ cd nogit
  $ mkdir .hg
  $ echo git >> .hg/requires
  $ hg status
  abort: repository specified git format in .hg/requires but has no .git directory
  [255]
  $ git config --global init.defaultBranch master
  $ git init
  Initialized empty Git repository in $TESTTMP/nogit/.git/
This status invocation shows some hg gunk because we didn't use
`hg init --git`, which fixes up .git/info/exclude for us.
  $ hg status
  ? .hg/cache/git-commits.sqlite
  ? .hg/cache/git-commits.sqlite-shm
  ? .hg/cache/git-commits.sqlite-wal
  ? .hg/requires
  $ cd ..

Now globally enable extension for the rest of the test:
  $ cat <<EOF >> $HGRCPATH
  > [extensions]
  > git=
  > [git]
  > log-index-cache-miss = yes
  > EOF

Test some edge cases around a commitless repo first
  $ mkdir empty
  $ cd empty
  $ git init
  Initialized empty Git repository in $TESTTMP/empty/.git/
  $ hg init --git
  $ hg heads
  [1]
  $ hg tip

  $ cd ..

Make a new repo with git:
  $ mkdir foo
  $ cd foo
  $ git init
  Initialized empty Git repository in $TESTTMP/foo/.git/
Ignore the .hg directory within git:
  $ echo .hg >> .git/info/exclude
  $ echo alpha > alpha
  $ git add alpha
  $ gitcommit -am 'Add alpha'
  $ echo beta > beta
  $ git add beta
  $ gitcommit -am 'Add beta'
  $ echo gamma > gamma
  $ git status
  On branch master
  Untracked files:
    (use "git add <file>..." to include in what will be committed)
   (?)
  	gamma
  
  nothing added to commit but untracked files present (use "git add" to track)

Without creating the .hg, hg status fails:
  $ hg status
  abort: no repository found in '$TESTTMP/foo' (.hg not found)
  [10]
But if you run hg init --git, it works:
  $ hg init --git
  $ hg id --traceback
  heads mismatch, rebuilding dagcache
  3d9be8deba43 tip master
  $ hg status
  ? gamma
Log works too:
  $ hg log
  changeset:   1:3d9be8deba43
  bookmark:    master
  tag:         tip
  user:        test <[e-mail]>

  date:        Mon Jan 01 00:00:10 2007 +0000
  summary:     Add alpha
  


and bookmarks:
  $ hg bookmarks
   * master                    1:3d9be8deba43
  $ hg up master
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg bookmarks
   * master                    1:3d9be8deba43

diff even works transparently in both systems:
  $ echo blah >> alpha
  $ git diff
  diff --git a/alpha b/alpha
  index 4a58007..faed1b7 100644
  --- a/alpha
  +++ b/alpha
  @@ -1* +1,2 @@ (glob)

  +blah
  $ hg diff --git
  diff --git a/alpha b/alpha

  +++ b/alpha
  @@ -1,1 +1,2 @@
   alpha

Remove a file, it shows as such:
  $ rm alpha
  $ hg status
  ! alpha
  ? gamma

Revert works:
  $ hg revert alpha --traceback
  $ hg status
  ? gamma
  $ git status
  On branch master
  Untracked files:
    (use "git add <file>..." to include in what will be committed)
   (?)
  	gamma
  
  nothing added to commit but untracked files present (use "git add" to track)

Add shows sanely in both:
  $ hg add gamma
  $ hg status

  $ hg files
  alpha
  beta
  gamma
  $ git ls-files
  alpha

    (use "git restore --staged <file>..." to unstage) (?)
    (use "git reset HEAD <file>..." to unstage) (?)

  	new file:   gamma
  

forget does what it should as well:
  $ hg forget gamma
  $ hg status
  ? gamma
  $ git status

  Untracked files:
    (use "git add <file>..." to include in what will be committed)

clean up untracked file
  $ rm gamma
