Start by reproducing `beet -vv im .` with the `musicbrainz` plugin and the release ID `1445701d-2b65-45ea-9e1d-67f15f049ed3`. The payload names no source files or tests, so trace the verbose MusicBrainz lookup and candidate extraction first. Done means the specified release is returned with its associated tracks instead of `No tracks` and `No matching release found`.
