caches: stop warming the cache after changegroup application

Now that we garantee that branchmap cache is updated at the end of the
transaction we can drop this update. This removes a problematic case with
nested transaction where the new cache could be written on disk before the
transaction is finished (and even roll-backed)

Such premature cache write was visible in the following test:

* tests/test-acl.t
* tests/test-rebase-conflicts.t

In addition, running the cache update later means having more date about the
state of the repository (in particular: phases). So we can generate caches with
more information. This creates harmless changes to the following tests:

* tests/test-hardlinks-whitelisted.t
* tests/test-hardlinks.t
* tests/test-phases.t
* tests/test-tags.t
* tests/test-inherit-mode.t

Corrupt an hg repo with a pull started during an aborted commit
Create two repos, so that one of them can pull from the other one.

  $ hg init source
  $ cd source
  $ touch foo
  $ hg add foo
  $ hg ci -m 'add foo'
  $ hg clone . ../corrupted
  updating to branch default
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo >> foo
  $ hg ci -m 'change foo'

Add a hook to wait 5 seconds and then abort the commit

  $ cd ../corrupted
  $ echo "[hooks]" >> .hg/hgrc
  $ echo 'pretxncommit = sh -c "sleep 5; exit 1"' >> .hg/hgrc

start a commit...

  $ touch bar
  $ hg add bar
  $ hg ci -m 'add bar' &

... and start a pull while the commit is still running

  $ sleep 1
  $ hg pull ../source 2>/dev/null
  pulling from ../source
  transaction abort!
  rollback completed
  abort: pretxncommit hook exited with status 1
