  Fix #1804 - mid_registrar_save() should save new contact from register following an unregister.

When using `sql_mode` is set to `SQL_WRITE_BACK` and  `rr_persist` is `RRP_LOAD_FROM_SQL` contacts are not
immediately deleted from memory, contacts are marked `expires = UL_EXPIRED_TIME`. So when a `REGISTER` request
is received following an UNREGISTER, do not return the previous contact marked for deletion.

Returning the previous contact record, could have potentially lead to a crash, if opensips would free the contact
record while mid_registrar would retreive that using `get_ucontact()`.
