Summary:                    [patch] SIP autocreate peers registered when request
to unregister
Description: 
When autocreate is enabled and a peer is *not* registered, and such a peer
sends a REGISTER message with the "Expires: 0" header (to indicate it wants
to unregister), the peer is apparently registered and then partially(?)
unregistered:
 * There is a NOTICE-level option poke message;
 * The sequence of PeerStatus manager events shows 3 events:
   1. Unregistered (that's expected)
   2. Registered (that's not)
   3. Reachable

  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.
