Subject: data: miscellaneous cleanup for withOtherReleases logic

Defines withOtherReleases in terms of new function
withAllReleases (also exposed as Track.allReleases),
in turn based on new property Track.secondaryReleases
(of the main release), which is a reverse ref list,
reverse.tracksWhichAreSecondaryReleasesOf().
