[antoijo]

When adding items in trackless with the add function and the Uris parameter. The deprecated parameter uri is still sent and cause an error in Mopidy :

When removing the uri parameter in tracklist.py on line 112 everything works fine.

return self.mopidy_request('core.tracklist.add', tracks=tracks, at_position=at_position, uris=uris, **options)
