Usually the screen is woken up before the shield is deactivated, but
it is also possible to unlock the session programmatically via the
org.gnome.ScreenSaver D-Bus API.
The intention is very likely not to unlock a turned off screen in
that case. Nor does it seem like a good idea to change the lock
state without any indication.
Waking up the screen is more likely to meet expectations and is
more reasonable too, so do that.
