Small optimization for Twig_NodeTraverser::traverseForVisitor
During traversing a node tree `Twig_NodeTraverser::traverseForVisitor` (`Twig_NodeVisitorInterface::leaveNode`) often returns a same child node (a same object). So, there is no need to set it back to its parent.
This PR adds a check if a child node was changed. With this check a lot of calls to `Twig_Node::setNode` will be skipped.
Closes #2665
