Fixed crash which occurs when switching between video clips

When Phonon::MediaObject::setCurrentSource() is called when the MediaObject is connected to a Phonon::VideoWidget, the MMF::AbstractVideoOutput pointer is propagated inside the backend from the first MMF::AbstractVideoPlayer to the second. If the VideoWidget is subsquently re-sized, the code path enters the ScaleFactors branch of the MMF::SurfaceVideoPlayer::handleParametersChanged function. At this point, m_displayWindow is still set to the inital null value, and the assertion therefore fails. This change ensures that m_displayWindow is updated before attempting to apply the scale factor change. Task-number: QTBUG-11377 Reviewed-by: Thierry Bastian
