Bug 33864: Set default date in all acqcreateitem scenarios

Bug 33864: Set default date in all acqcreateitem scenarios

On b0aab2aeef9a025d3907d0b723b5ea71eaf94542 the flatpickr default to
'today' was restored, but only for acqcreateitem='ordering'. This patch
moves the initialization to a different stop for broader reach.

To test:
1. Have 3 baskets on with each setting:
   - create_item = 'cateloguing'
   - create_item = 'ordering'
   - create_item = 'receiving'
2. Close those baskets
3. Go to 'Receive shipments'
4. Choose things from the 3 baskets and then 'Receive selected'
5. Navigate through the different orders
=> FAIL: Only the one that has items created on ordering has the date
filled by default
6. Apply this patch
7. Reload the page
8. Repeat 5
=> SUCCESS: Dates are pre-filled!
9. Sign off :-D
