> Migration should be smarter at adding new relationships to model. E.g. I have Artist and Painting with rel toArtist. Now I add new column ARTIST_NEW_ID to database, and do migrate. It fails, because auto-generate relationship with name "toArtist" already exists. We should check it and insert it with name "toArtist2"
