Description: fix appendChildNode() call
 The QSGNode::appendChildNode() method checks that its parameter must
 not have a parent. Before this patch we always called appendChildNode()
 on a node that already had parent, which was always leading to ASSERT
 in a debug build.
 .
 Seems that the right approach would be to call this method, if the
 node *does not* have a parent.
