  b2b_entities/logic: properly reply to canceled/expired entities

Generate a 487 reply from opensips to the server entity if:
* no final reply from the client entity received and the tuple
  expires after a CANCEL request has been received;
* a 200 OK has be received after a previous CANCEL request.

Also, reply with 408 to the server entity if the tuple expires and no
final reply from the client entity has been received.

fixes.

  Log Message:
  -----------
  b2b_entities/logic: fix a race condition with simultaneous reINVITEs

Fix behavior when receiving reINVITES from the connected entities at the
same time, one replied with 491 and the other with 200OK. The 200 OK
would not be passed to the other entity and the tuple would never be
deleted in this case.

Thanks to David Escartin from Sonoc for reporting and testing the fix.
