Fix crash for artists without tracks #256

Closed XDjackieXD closed 6 years ago

XDjackieXD commented 6 years ago

As described in #103, loading the metadata of artists without tracks crashes while parsing the top tracks. This fix just returns an empty Vec in case an artist doesn't have any tracks.
