window: Do not restore shortcuts on a NULL window

The "force restore shortcuts" being triggered by a key-combo, there is
no guarantee that the currently focused window is actually non-NULL in
which case we would crash.

Make sure there is a window currently focused before trying to restore
the shortcuts on that window.
