    GtkImage: Move g_clear_object() to gtk_image_finalize()
    
    This moves the freeing of the icon_helper from the destory to the finalize
    function to avoid segfaults when trying to access a destroyed object before it
    is disposed. This often happens in signal handlers which get called
    asynchronously after destroy.
