    tdf#129809 qt5: take a reference in case m_aContents is replaced
    
    This takes over Caolán's solution for gtk3 from
    dbcdc5cd98df5756a96559e467cad95c629343ca
    ("tdf#129809 take a reference in case m_aContents is replaced")
    for the qt5 case as well, to prevent that the XTransferable
    is destroyed along with the Qt5MimeData object as new QMimeData
    are set in the clipboard, as follows:
