This seriously changes the behavior. Does the bug require that?

This change solves a separate problems and I filed another issue. It clears
playlist on click the Play button in the file manager or click on a file in the
dowsnloads page.

   current_playlist_.push_back(MediaUrl(url));
   current_position_ = current_playlist_.size() - 1;
   pending_playback_request_ = true;
   NotifyPlaylistChanged();
