When adding a a release, the RE won't update track artists properly.
Steps to duplicate:
- Go to http://musicbrainz.org/release/add?artist=3d4198c9-dc74-4eeb-ab90-68cc2d45b287
- Type in a release name (e.g. "test").
- Go to the tracklist tab and enter a track or two.
- Go back to the release information tab, and change the artist credit: "James Dooley, Credited as Jim Dooley"
- Go back to the tracklist tab.
Note that the "Credited as" information hasn't changed on the tracks.
