Replace hide() call (present in itemViewKeyboardEvent since Qt 4.5)
by reject(). Add signal spy to existing test function.
QDialog doc states that reject() will always be called on Key_Escape.
hide() is not enough: it makes exec() terminate and return the proper
value, but the signals finished(int) and rejected() will not be sent.
