    search-controller: Remove the vfunc for the default handler
    
    This is a final class, so there wasn't going to be any sub-class that
    would want to override the default signal handler. We might still want
    a default handler for PhotosSearchController itself, but we can
    achieve the same effect with a simple private function. It is a small
    price to pay for being able to use G_DECLARE_FINAL_TYPE.
