    app: don't leak all cached GtkTreeIters in container views
    
    This is evil: the hash table of "insert_data" is created on demand
    when GimpContainerView API is used, using a value_free_func that is
    set in the interface_init functions of its implementors. Therefore, no
    GimpContainerView API must be called from any init() function, because
    the interface_init() function of a subclass that sets the right
    value_free_func might not have been called yet, leaving the
    insert_data hash table without memory management.
    
    Call GimpContainerView API from GObject::constructed() instead, which
    runs after everything is set up correctly.
