* Attempt to make the m_webFrame null pointer checking consistent. Always check for
  m_webFrame. It should get set by the QWebFrame with the FramerLoaderClientQt::setFrame
  call and should stay valid until the destruction of the QWebFrame.
* Currently the same checking is not needed for m_frame as it will only set to 0 in
  FrameLoaderClientQt::frameLoaderDestroyed and should be not 0 because of the setFrame
  initialisation.
