Signed-off-by: Katrin Fischer <Katrin.Fischer.83@web.de>
Testing plan copied from bug:
- Create a new basket for a bookseller
- Create two new order in this basket. The orders must have a price or else
they won't be shown in the "Late orders" report.
- Delete one of the two orders.
- Close the basket
- Check for late orders and use "0 days ago" as a filter date.
- The deleted item appears in the report.
