Bug 13457 - Followup for CPL and S codes

Bug 13457 - Followup for CPL and S codes

Based on comment #3, this corrects CPL and S issues if they do
not exist in the DB.

TEST PLAN
---------
0) Backup your DB.
1) Clear CPL and S from your DB.
   - delete from borrowers where categorycode='S';
   - delete from categories where categorycode='S';
   - delete from borrowers where branchcode='CPL';
   - delete from branch where branchcode='CPL';
2) prove t/db_dependent/Suggestions.t
   -- This should fail.
3) Apply patch
4) prove t/db_dependent/Suggestions.t
   -- This should work.
5) Intentionally add categorycode 'S' and branchcode 'CPL' back
   into the database.
6) prove t/db_dependent/Suggestions.t
   -- This should work.
7) run koha qa test tools.
8) Restore your DB :)
