Drop redundant display of album artist in track lists

See merge request funkwhale/funkwhale!1041

* The album artist is already printed at the top (`Album containing N tracks, by Album Artist`), so printing it in the track list is redundant
* For collaboration tracks (X feat. Y), the displayed Artist entry will contain the album artist twice (e.g. "X / X feat. Y")
* Printing only the track artists is consistent with the way songs are displayed in the playback queue
