    grltrackerplaylists: Add location filter to Playlist
    
    Since 41c60ec7c35f all the songs in the Playlist are matched to a songs
    in the main songs model. The main songs model only contains songs from
    the filtered location, so any songs in a playlist outside of this
    location crashes Music as the hash match fails.
    
    Add a location filter to the songs queries in Playlist to prevent this
    from happening.
