Fix message for SuperordinateDomainInPendingDeleteException

The StatusProhibitsOperationException superclass constructor just wants a raw message to return to the client, so we should pass it an explanation rather than just the superordinate domain name.  In fact, I think the superordinate domain name isn't really necessary since it should be obvious from the hostname in the create/update request what the superordinate domain would be.
