Bug 15202: Fix date display when transferring an order

Bug 15202: Fix date display when transferring an order

The date a basket was created was not displayed
according to the dateformat system preference.

Also fixes wording of the message shown when there
are no baskets for a chosen vendor.

To test:
- Create an order with an order line
- Click on the "Transfer" link on the basket
  summary page
- Search for a vendor without open baskets
- Verify change of message shown:
  "There are no open baskets for this vendor."
- Choose another vendor with open baskets
- Verify the creation date of the basket is
  displayed correctly formatted.

Followed test plan, works as expected.
