Bug 23177: (QA follow-up) Remove subtest txn_begin and rollback

This resolves:
DBIx::Class::Storage::txn_rollback(): A txn_rollback in nested transaction is ineffective! (depth 1)
Removing unneeded subtest txn's. We should probably add them everywhere or
just at global level.

Test plan:
With all three patches applied, run Circulation.t a few times.

Bug 23177: (RM follow-up) Further test clarifications

This patch makes a few minor improvements to Circulation.t

   subtests.
2) Adds output messages to some tests where they were missing.
