Bug 36581: Define ymd in scope for checkouts table

Test plan:
1. Find or create an item with a public or nonpublic note
   (in KTD default data, items on biblionumber 12 have notes already)
2. Check the item out to a patron
--> Checkouts table loading never completes
--> Browser console shows: "Uncaught ReferenceError: ymd is not defined"
3. Apply patch and clear browser cache
4. Refresh the page
--> Checkout table loads and console error is gone
