util: don't assume that converted rev is an svn rev Summary: In repos where converted revisions come from different sources it's not nice of hgsubversion to assume that all converted rev are coming from SVN. Test Plan: Ran all current tests, nothing is broken. Not sure how to test new behaviour withour much overhead. I suppose I could write something that overrides commit extras
