    grltrackerplaylists: Correctly add songs to user playlists
    
    When adding songs to a user playlist, there are two steps:
    1. Insert the songs in the playlist (update Tracker database)
    2. Query these songs to add them to the playlist's model (and thus
    display them in GNOME Music)
    
    The second step always fails because the filter clause uses the wrong
    media id. Indeed, there are two ids to consider: the id of the song
    and the id of the entry in the playlist. The filter clause fails
    because it uses the id of the entry instead of the id of the song.
    
    Fix the issue by using the song id.
