Bug 34908: Sort item types alphabetically by description when adding a new empty record as an order to a basket

To test:

1. Go to Koha administration -> Item types. Add a new item type "B" with the description "Test" so it will be obvious if it is sorted by the code "B" instead of the description "Test".
2. Go to Acquisitions. Add to a basket from a new empty record
3. In the Catalog details section, note the Item type dropdown. Confirm your "Test" item type, is showing near the top of the list, indicating it has been sorted based on the code "B"
4. Apply patch and restart services. Refresh the page.
5. Open the Item type dropdown again and confirm your "Test" item type is showing in the expected alphabetical order.
