Lidarr's metadata is keyed by MusicBrainz release group, but re-acquisition
requested albums by their release id, so every add came back "not found".
- Sweeper requests an album by its tag-supplied release group, else the one
MusicBrainz names (cached onto the album). An album MusicBrainz cannot name
is skipped and counted, with no attempt spent.
- Reconciler: an add refused as not found re-reads the request's album id as
a release (library first, then MusicBrainz), rewrites the request to the
group and adds again. This repairs the requests already stored.
- Completion matches an album by release id or release group, and only once a
track of it is on disk, so a re-acquisition request no longer completes
against the row of the album it is trying to bring back.
Closes#5241.
