SortOrder is not synchronized between servers

[alex-solutionlab]

Description
When pushing a parent node with the "children include" option, the SortOrder does appear in the "changes" menu however, on an actual push, the target server's "children" retain the old sort order.

To Reproduce
Steps to reproduce the behavior:

1. Prepare 2 servers. (I've used clean install v15 + starter kit)
2. On server#1 select a parent node with children
3. Do a first push to a server#2 with "include children" option selected
4. Sort the children on server#1 in any way you want
5. Push parent with children to server#2

Expected behavior
The server#2 should have the children sorted in the exact same way as the server#1

Actual behaviour
The server#2 retains the old sort of the children nodes.
