[gnome-music/wip/jfelder/playlistview-songs-count: 10/10] playlistview: Hide songs_count label on loading

    playlistview: Hide songs_count label on loading
    
    With the new playlistcontrols logic, the _songs_count_label is visible
    when a playlist is populated. This effect can be disturbing: it
    behaves like a counter.
    Hide the count label when a playlist is being loaded and show it once
    the operation is finished.
