Title: Children order is incorrect when not using 'nodeOrder' option.

I am sorting/paginating the tree children on the server, so specifying a sort field in the template is not needed.

When I left the node-order option out, I wound up getting `orderBy:"undefined"` in the generated ng-repeat element.

This pr fixes the problem by only including the `orderBy` filter if the `node-order` attribute is set
