Unpairing a stereo pair crashes sonos-web

[bmn001]

Stereo-paired speakers (where one speaker is Left, one is Right) show up in the UI as if it's a room that's been paired with itself.

The name of the room will show up as "Roomname + 1" and the room that it's paired with will also be "Roomname".

In this example I have two Ikea Symfonisk speakers in Office, one is left and one is right:

If I click the X as if I were to ungroup this room, sonos-web crashes:

/sonos-web/server/node_modules/sonos/lib/services/Service.js:87
              myError = new Error('upnp: statusCode 500 & upnpErrorCode ' + error.response.data)
                        ^
