BUG/MEDIUM: stconn: Don't forget to wakeup applets on shutdown

When SC's shudown callback functions were merged, a regression was
introduced. The applet was no longer woken up. Because of this bug, an
applet could remain blocked, waiting for an I/O event or a timeout.

This patch should fix the issue #3301.

No backport needed.
