Title: Fixes session_end message printing

This should solve the root cause behind the problem noted here:
https://groups.google.com/group/sage-devel/msg/48d517b2f5c2cb5c

Basically, the session_end message was being sent but not
displayed, so users would think that interacts were still active
when they were not.
