Fixes crash when setting geometry on an obscured window.

Since Qt on Symbian now destroys the backing store when it gets hidden
or obscured we need to be careful not to use functions like moveRect()
when we don't have a backing store since this function is really a
backing store optimization and therefore assumes one exists.
