Fixed memory leak in QMessageBox::setInformativeText in Symbian

The Symbian implementation of QMessageBox::setInformativeText was
taking the text from a QLabel and using it in a QTextBrowser, leaving
the QLabel un-parented and therefore leaking. This is fixed by setting
the QMessageBox as the QLabel's parent
