"Get Metadata" from Discogs adds " , " after each artist name of some releases

1. On _some_ discs where multiple (joined) artists are listed per track, XLD 
will add " , " at the end of the artist name for each track, when data is 
retrieved with "Get Metadata frm URL…" from Discogs.

2. Examples of this behaviour:
http://www.discogs.com/Rhythm-Sound-W-The-Artists/release/191850
http://www.discogs.com/Various-Ouzbekistan-Les-Grandes-Voix-Du-Pass%C3%A9-1940-1
965/release/1270080

3. XLD however works as expected on:
http://www.discogs.com/Various-An-Anthology-Of-Noise-Electronic-Music-Fourth-A-C
hronology-1937-2005/release/693283
http://www.discogs.com/Various-Rez-Gamers-Guide-To-/release/178746
http://www.discogs.com/Various-The-Secret-Museum-Of-Mankind-Music-Of-East-Africa
/release/2972477
