    xrandr: Register our DBus API only after all other initialization
    
    Otherwise we risk being called and not have all out internal state
    ready (e.g. priv->rw_screen being NULL) leading to crashes.
    
    We also need to disown our well known name on stop() since we'll
    reaquire it if start() gets called again.
