Bug 11218: fix Item Due notices not being generated

To test:
- Check out at least 3 items, due dates should be today, sometime in
  the past and one day after tomorrow.
- Edit the message options - activate DUE and PREDUE notices with
  days in advance = 2
- Run the advance_notices.pl script with -v -c
  Result: Only a PREDUE notice is generated
- Run the advance_notices.pl script with -v -c -m 2
  Result: Only the PREDUE message is generated correctly.
- Run t/db_dependent/Circulation.t
  - without first patch: all tests pass.
  - with first patch: some tests will fail.
- Apply patch.
- Rerun script, now PREDUE and DUE notices should be
  generated.
- Run t/db_dependent/Circulation.t again, all tests should pass.

Add more items with different due dates, rerun and check results.

Run t/Circulation.t to confirm all tests pass.
- Apply the patch
