fix memory leak of QAccessibleWidget

in topLevelObjects() we should use "root->object()" instead of
"w->accessibleRoot()->object() to get the object attached to the
accessible interface. This is because "w->accessibleRoot()"
will create a new QAccessibleWidget(or its subclass) object
and this object is never released.
