revset: handle wdir() in `roots()`

This is already handled in `heads()`, and both are needed to determine if a set
is contiguous.

I'm guessing the `0 <= p` check was to try to filter out the null revision, but
it looks like that comes through in the corner case of a new repo with no
commits.  But that was already the case, as shown by the tests.

Before (on a clone of hg):

    $ python3.8 hg perf::revset --config extensions.perf=contrib/perf.py 'roots(all())'
    ! wall 0.059301 comb 0.040000 user 0.040000 sys 0.000000 (best of 100)

After:

    $ python3.8 hg perf::revset --config extensions.perf=contrib/perf.py 'roots(all())'
    ! wall 0.059387 comb 0.060000 user 0.060000 sys 0.000000 (best of 100)

Test update.requiredest
  $ cd $TESTTMP
  $ cat >> $HGRCPATH <<EOF
  > [commands]
  > update.requiredest = True
  > EOF
  $ hg init repo
  $ cd repo
  $ echo a >> a
  $ hg commit -qAm aa
  $ hg up
  abort: you must specify a destination
  (for example: hg update ".::")
  [10]
  $ hg up .
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ HGPLAIN=1 hg up
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg --config commands.update.requiredest=False up
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved

  $ cd ..

Check update.requiredest interaction with pull --update
  $ hg clone repo clone
  updating to branch default
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ cd repo
  $ echo a >> a
  $ hg commit -qAm aa
  $ cd ../clone
  $ hg pull --update
  abort: update destination required by configuration
  (use hg pull followed by hg update DEST)
  [10]

  $ cd ..

update.requiredest should silent the "hg update" text after pull
  $ hg init repo1
  $ cd repo1
  $ hg pull ../repo
