tests: Prepare test_meta_receipt to test more credits and fallbacks.

I'm getting to ready to extend this hook to deal with income receipts as
well as expense receipts. These changes let me write the tests in a more
declarative style, so I don't have to duplicate them all again to test
credits as well as debits.

Note that we're only testing debits right now, just like the existing tests,
because the default check_type for check() is PostType.DEBIT. Part of making
the changes will be changing that to PostType.BOTH.
