Send server change events to subscribers, when default nodes change due to some nodes being added/removed/changed, also if there is no metadata change. Make sure the event is consistent with the result from find_device at the time. Previously, these were not necessarily sent, or information from find_device immediately after the event might not reflect the change yet.
