Martin Gräßlin be7e9249cf [globalaccel] Ensure we don't call into deleted InputRedirection on shutdown
KGlobalAccel plugin gets deleted by a global static. At that point
InputRedirection is already deleted but the plugin holds a static pointer
to it.

This change connects to the deleted signal by InputRedirection and
ensures that the plugin doesn't call into the deleted code any more.
