Doesn't work with recent beta

[dkadioglu]

Hi,

since yesterday there is a new beta (http://repository.spotify.com/pool/non-free/s/spotify-client/spotify-client_1.0.13.111.g6bd0deca_amd64.deb) which brings back DBUS/MPRIS2. But PlayBar doesn't recognize Spotify running. Could you please have a look into that?
The same applies to PlayBar2.

Thanks!
