    artistsview: Do not emit row-activated signal on launch
    
    Emitting this signal before the ArtistsView is visible triggers some
    Gtk errors: `Gtk-CRITICAL gtk_widget_event: assertion
    'WIDGET_REALIZED_FOR_EVENT (widget, event)' failed`
    
    Directly calling the associated callback fixes the issue.
