    app: don't use g_free() as key_destroy_func in a GType-keyed hash table
    
    This would have crashed if we ever replaced or removed something in
    that hash table. Instead, use g_object_unref() as value_destroy_func
    because the table keeps GimpContainers which we would leak if we ever
    removed anything from the table.
