    application: Clean up OffsetController signals
    
    Failure to clean up the OffsetController signals led to
    Embed._onItemCountChanged and, ultimately, Embed._hideNoResultsPage
    being called with an invalid GtkStack if launch-search was received
    before the inactivity-timeout expired. This is why we got this WARNING
    in the console:
      Child name 'view' not found in GtkStack
