Fix a crash bug in LightmapGI::_assign_lightmaps triggered after reparenting
After reparenting the LightmapGI node, the following
node
would be initialized to null:Node *node = get_node(light_data->get_user_path(i));
Which would then crash when de-referenced further down. This fix detects which the node has been reparented and clears its users.
