imo i think the actual fix is to not call update_plug in add_non_managed_plug and tear_down_plugs for the unmanaged plugs, but this theoretically does the same thing. We might run into some edge case later on because the non-managed plugs are added to plugs_by_type and _by_name earlier than the managed plugs, but it's probably fine

I'll try to implement when I've got more time :)
