IMS-VT: CameraCapabilities are not passed to UI.

Sometimes, during conference merge scenario, callbacks for VideoCall
might get unregistered while enabling camera. This prevents camera
capabilities from propagated to InCallUI and thereby prevents startng
of camera preview.
After conference merge videoCall is changed and we started using
the new videoCall before its callback is registered
To fix this storing previous videoCall and comparing with latest
videoCall.
