This is a seeming omission I noticed while cleaning things up; if we're actually
using a Google-based service, and listening for changes to the Google URL, we
should ensure the GoogleURLTracker actually checks for URL updates.

     google_url_updated_subscription_ = google_url_tracker->RegisterCallback(
         base::Bind(&NavigationCorrectionTabObserver::OnGoogleURLUpdated,
                    base::Unretained(this)));
   }
 }
 
 NavigationCorrectionTabObserver::~NavigationCorrectionTabObserver() {
