tls: logging for session resumption

tls: logging for session resumption

We assume session resumption has occurred if the Client Hello message
included a session id, we have not seen the server certificate, but
we have seen a Change Cipher Spec message from the server.

Previously, these transactions were not logged at all because the
server cert was never seen.
