Remove ssl3_check_finished.

ssl3_get_new_session_ticket is sensible and fills in a session_id for stateless
sessions, so the resumption will already be detected at this point. Remove the
codepath in ssl3_client_hello which allows for resuming sessions with empty
session_ids. The rest of the code doesn't allow it either.

This removes another codepath where we potentially probe a Finished message
early.
