Don't activate transient parent if it was closed meanwhile

Closing a window while a popup is open should not trigger an activation event
when the popup is closed.

Prevents QGuiApplicationPrivate::focus_window from being changed to a stale window,
which happens inside QGuiApplicationPrivate::processActivatedEvent().
