Spotify Connect: after disconnect via Spotify app current title is still displayed

[rayddorf]

When you disconnect Spotify Connect, the sound is played elsewhere, but in volumio it still looks as if it is still connected. Player controls in this state still work, so you can play/pause, skip etc. inside volumio and it affects the playing on the other device.
There is no way to continue playing in volumio, except using the spotify app to establish a new connection
