Apply filters to the results

[Dremora]

1. Filter by amount of tracks:
   • If the amount of selected tracks equals the amount of tracks on the release, keep the release.
   • Otherwise, keep media with the same amount of tracks.
2. When tagging by Disc ID, an additional filter applies:
   • For each medium, if it has a requested Disc ID, keep it.
3. If release ends up with no media left, drop it.

#1 can partially be done using search params, thus the server will not yield releases with no matching discs, and #3 is not needed.
#2 will be done when MBS-2306 is closed. Moving to 0.4
