    [ThickClient] Ensure track filter actions updated (bgo#635426)
    
    We weren't updating the track actions when the track model changed
    (which it does when you right click an album, say).  The effect of this
    was the remove/delete confirmation dialog's track count wouldn't get
    updated.
