    window: Do not remove static playlists when pressing Delete
    
    The Delete action is disabled for static playlists, however there is an
    inconsistency, because it's still possible to remove such a playlist using
    the Delete key.
    
    This patch introduces a wrapper over the _on_delete_activate method to
    ignore static playlists when pressing the Delete key.
