We now include base FileDiff ID (where appropriate) when commenting on
commit ranges. This allows us to create comments on FileDiffs with a
base FileDiff.

  • Commented on a FileDiff with a base FileDiff and saw the correct
    result in the database.
  • Refreshed the diffviewer and saw that comment flag render
    correctly.
