Doc & menubar hidden for QtDemo after switching back from fullscreen

The problem here was fix for bug QTBUG-8933. In order to fix that
bug we added a new call to the SetSystemUIMode(...) system call, but
I forgot to update the status inside Qt, so the system didn't know it
was in full screen mode.
