#64 Downloading an artist misses albums where the artist is only a contributor

Example: https://www.deezer.com/us/artist/96330612 The 2 newest singles aren't downloaded because this artist is listed only as a contributor on the album and tracks. This is probably a deezer bug because apple and spotify both list the 2 artists as the main artists. This appears to be a wide-spread issue on deezer, where multi-artist albums/tracks are converted into single artist+contributors. But even if the artist was only a contributor, I'd expect it to be downloaded.
