Undo deleting a Set or Map member variable will add it back to datatable in reverse order if it was changed

When undoing the deleting of a struct set or map variable, the order of the entries will be reverse in any datatable that's based on the struct. This only occurs if the entries have been modified in the datatable.

This doesn't occur with arrays

1. Open QAGame in editor.
2. Create a new datatable based on TestContainerStruct.
3. Open the datatable.
4. Add a row.
5. Change the Key values of NameMap.
6. In TestContainerStruct, delete the NameMap member variable.
7. Undo.

RESULT

In the datatable, the NameMap entries will be in reverse order
