log: fix log -rREV FILE when REV isnt the last filerev (issue2492)

Regression from 99cafcae25d9. That previous commit is not supposed
to affect log calls without --follow, so we step out of this
codepath if follow is not True, and it's enough to fix the
regression.

When --follow is given, we fix the issue by taking into account
changesets that have a rev > maxrev to build the filegraph: even if
those files are not included in the final result, it's still needed
to walk correctly the graph from the end of the filelog to minrev, to
track accurately renames.
