This setclientid_confirm case should allow the client to change
callbacks, but it currently has a dummy implementation that just turns
off callbacks completely. That dummy implementation isn't completely
correct either, though:
- There's no need to remove any client recovery directory in
this case.
- New clientid confirm verifiers should be generated (and
returned) in setclientid; there's no need to generate a new
one here.
