Artist MBID lookup failed due to multiple relations

[derat]

The artist MBID wasn't found while I was seeding https://mpsc.bandcamp.com/album/days-as-echoes. I see this in the logs:

Failed getting artist MBID from https://mpsc.bandcamp.com/: got 3 relations for URL

There's already a TODO in mbdb/db.go about figuring out how to handle this case.

Here's the XML from https://musicbrainz.org/ws/2/url?resource=https%3A%2F%2Fmpsc.bandcamp.com%2F&inc=artist-rels (after manual reformatting):

Maybe I should just choose the MBID corresponding to the name that's closest to the artist name from Bandcamp.
