test(journal_entry): pin transaction-currency conversion in GL entries

Browse Source 
Mutation testing on gl_composer surfaced that the foreign-row
debit/credit_in_transaction_currency conversion (amount / exchange_rate) was
unverified -- a / vs * bug survived. Assert those fields in test_multi_currency
and add a foreign-debit case so both conversion directions are now caught.
