ChangeBundle: Ignore null originalSubject in ReviewDb changes

Browse Source 
Original subject is a nullable field added relatively recently, so
there are many changes that don't have it set. In NoteDb we
reconstruct this by looking at the patch set commit, so it is always
present. Don't consider this a difference between ReviewDb and NoteDb.
