  Don't recreate peer, when responding to a repeated deregistration attempt.
  
  When a reply to a deregistration is lost in transmit, the client retries the
  deregistration.  Previously, this would cause a realtime/autocreate peer to be
  loaded back into memory, after it had already been correctly purged.  Instead,
  we just want to resend the reply without loading the peer.
