Bug 34232: Make dropdown on additem page rescept display order

To test:
1. EnableItemGroups
2. Find a record and add some new item groups with different display orders
3. Now edit an item on the record and scroll down to the dropdown underneath "+ Add to item group"
4. Notice that the values in the dropdown do not respect the display order.
5. Apply patch and restart_all
6. The display order should now be respected
