Bug 26190: Allow to close a basket with only cancelled order lines

Bug 26190: Allow to close a basket with only cancelled order lines

At the moment there are several cases, when closing a basket is not
possible:
- when there are no order lines in it
- when there are order lines with uncertain prices
- when the basket is marked as a standing order

The first case wasn't checked correctly as only pending/received
orders would be counted, but not cancelled orders.

To test:
- Create a basket
- Create an order line
- Verify the "close this basket" button shows
- Cancel the order line - the button disappears
- Apply the patch
- Verify the button appears and works now
- Create another basket - make sure you cannot close it
  without order lines
- Create an order line with uncertain price checked
  - you cannot close it
- Resolve the uncertain price - you can now close the basket.
