git: add debug logging when there's a mismatch in the cached heads list

The dag rebuild can be expensive, so let's try and avoid bugs where it
transparently rebuilds all the time for no reason. This would have
prevented the issue fixed in D8622.

  ? .hg/requires
  $ cd ..

Now globally enable extension for the rest of the test:
  $ echo "[extensions]" >> $HGRCPATH
  > echo "git=" >> $HGRCPATH

Make a new repo with git:
  $ mkdir foo
  $ cd foo
  $ git init

  abort: no repository found in '$TESTTMP/foo' (.hg not found)!

But if you run hg init --git, it works:
  $ hg init --git
  $ hg id --traceback
  3d9be8deba43 tip master
  $ hg status
  ? gamma
Log works too:
  $ hg log

  $ echo a >> alpha
  $ hg ci -m 'more alpha' --traceback --date '1583522787 18000'
  $ echo b >> beta
  $ hg ci -m 'more beta'
  $ echo a >> alpha
  $ hg ci -m 'even more alpha'
  $ hg log -G alpha
