Bug 28351: (bug 26261) Fix datepicker for dateformat ne mm/dd/yyyy

This patch restores the same code we have prior to bug 26261

0. Set dateformat to mm/dd/yyyy
1. Go to a patron detail page
2. Open the 'Restrictions' tab
3. Choose a future date in which the day is higher than 12
=> SUCCESS: The input has the date we chose
4. Set dateformat to dd/mm/yyyy
5. Repeat 3
=> FAIL: It sets the current date, the browser console shows an error.
