PadMessageHandler: Always save the author ID in the session info

Browse source 
Before, the author ID was only saved in the session info during the
initial CLIENT_READY, not when the client sent a CLIENT_READY due to a
reconnect. This caused the handling of subsequent messages to use an
undefined author ID.
