merge: update commitinfo from all mergeresults during bid merge During bid merge, it's not clear which commitinfo should be stored and which one should not. This depends on which side the bid merge chooses for a file. For this we will need to refactor bid merge code and commitinfo handling. For now, we just blindly updates info since we hardly have any users of commitinfo and this will help us in testing and clearing out further path.
