localrepo: recreate phasecache if changelog was modified (issue4855)

Because _phaserevs and _phasesets cache revision numbers, they must be
invalidated if there are new commits or stripped revisions. We could do
that by calling _phasecache.invalidate(), but it wasn't simple to be
integrated with the filecache mechanism.

So for now, phasecache will be recreated after repo.invalidate() if
00changelog.i was modified before.
