iOS: check if Qt has an active window before scrolling to cursor
In hybrid applications an external view can be first reponder. And when
that is the case, Qt will have no active windows and focusView will return 0.
We therefore need to protect scrollToCursor from this case, so it doesn't try
to access e.g focusView().window, which will lead to a crash.
