clone: make sure we warm the cache after a clone
This work around any deviciency/limitation of the clone process. In our case
this ensure the persistent nodemap exist with valid content.
Ideally, the cloning process would also do "the right thing". However since
older server will never be able to do "the right thing". The local workaround
will be necessary anyway.
I am not worried by the performance impact of this as `hg clone` is non-instant
on large repositories where is could matters. Warming the cache if they are
already correct is very fast. And if they are not already warm, this seems like
a good time to do so.
This impact various test as more cache are now warmed sooner, all the change
should be harmless.

$ 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 init
Initialized empty Git repository in $TESTTMP/nogit/.git/
$ git config --global init.defaultBranch master
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
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

Log works too:
$ hg log
