    tdf#136323 qt5: Remember accessible object
    
    'QAccessibleCache::insert' from the Qt library has a
    'Q_ASSERT' checking that the corresponding 'QObject' for
    which the 'QAccessibleInterface' provides information
    is actually the same as the object passed as a parameter:
    
        QAccessible::Id QAccessibleCache::insert(QObject *object, QAccessibleInterface *iface) const
        {
            // ...
            QObject *obj = iface->object();
    ->      Q_ASSERT(object == obj);
    
    However, 'Qt5AccessibleWidget::object' so far was always returning
    'nullptr', triggering this assert when using a Qt version
    not built with 'QT_NO_DEBUG'.
    
    To fix this, remember and return the object as needed.
