07bbe358 - Clean up a codepath that was only used for crypto messages

Clean up a codepath that was only used for crypto messages Transmission of encrypted messages was happening somewhat differently to normal messages. In particular, we weren't copying the 'unsigned' field when we got the remote-echo, which meant the 'sync' code didn't correctly match up the echo with the original. The separate codepath was becoming a thorn in my side, so fix things up to bring it back in line.
