    searchenginemodel: finalize search results
    
    It is necessary to signal the search engine that we are finished and
    that we found something for it to reliably show the results. It would
    sometimes work anyway since it is sufficient if any backend signals
    completion. However if GtkSearchEngineModel was the only backend
    returning results then things would break.
