Bug 27281: (follow-up) Clean up LostItem test

The LostItem test was rather messy, and wasn't actually testing much in
reality. This patch cleans it up and adds testing for transfer queue
handling of ListItem cancellations.

Test plan
1/ Confirm t/db_dependent/Circulation.t still passes
2/ Read the tests before and after and confirm that they test what is
required.
3/ Signoff
