crashes when opening from the peer picker on unity8 desktop

If camera-app is already running when selected in the peer picker, it switches to picking mode just fine. However if camera-app is not running, it crashes on startup when selected from the peer picker.

In order to get camera-app to show up in the peer picker, you need a deb built from my branch[1] and run the hook[2] manually once after installing the deb.
