    tracker-writeback: Use nmm:artist property to handle artist tags
    
    This nmm:artist was introduced in nmm:MusicPiece to distinguish the
    track artist (nmm:artist) from the performer (nmm:performer).
    nmm:artist property is now used to store all the artist information.
    
    See tracker commit eb9022c15514177d9561ff9f86e061e193f452da
