To reproduce:

• Go to https://musicbrainz.org/release/add?release-group=a3ea1232-72ac-4a71-8f5a-12c3c5622138
• Reuse the existing tracklist
• Open the track parser, make sure "Use track artists" is selected and then make sure "Lines contain track artists" isn't selected and parse the following:

  1. first
  2. second
  3. third

Expected result: Either: "Use track artists" depends on "Lines contain track artists" and when "Lines contain track artists" is not selected, the artist credits should not get changed, or: "Use track artists" is independent of "Lines contain track artists" and should not be disabled by unselecting "Lines contain track artists".

Actual result: All track artist credits are reset to the release artist credit.
