Bug 23091: Make relations more explicit
This patch simply makes the queries built for the ->debits and ->credits
relations in Koha::Account::Line more explicit.
Test plan
1/ Ensure tests continue to pass
2/ Run tests with DBIC_TRACE=1 DBIC_TRACE_PROFILE=console and note that
the related queries not include 'credit.' and 'debit.' as appropriate.
