Add checking "before" as child node

qquickitem_before_paintNode returns the transform node for the rectangle
as child node. But the node has no parent. It leads to following assertion
case at QSGNode::insertChildNodeAfter(). But, I tested it in release mode,
so no assertion happened. So, Some node not be able to add group node
from this cause.
