Reordering layer nodes by drag-drop, move up/down, add new etc. swaps layer attributes with wrong layers. This is due to mistake in map `new_by_old_map`. Values of this map is used as indices in src array. And keys are indices of dst array. Expected behavior is to copy attribute from old position (`layer_i_old`) of src array to new position (`layer_i_new`) of dst array. See: `array_utils::gather`. Noticed during !141772.
