Not all clients have an existing registry, and the registry generation number will not be updated for them. However, we would like to check for stale globals also elsewhere, eg. metadata, and it must work also in this case. To avoid failing to update client registry generation, on global addition which the client would see if it had a registry, send done message for the new global id instead.
