GStreamer: Always notify CameraBinSession if a device has been selected

CameraBinSession is never notified if a device
has been unplugged and replaced by new one with the same index.

Since QGstreamerVideoInputDeviceControl is for internal usage and
dependent classes already check against the device name, we don't
need to check it here.
