Log:
res_pjsip_registrar: Add Expires header to 200 OK if present in REGISTER.

Some implementations don't pay attention to the expires for individual contacts.
In this case they may consider the lack of an Expires header in the 200 OK as
unregistered. This change makes it so if an Expires header is present in the REGISTER
we will add one in the 200 OK.
