Log:
Improve transaction currency lookup by using the new account_or_default currency getter.

Previously, this could result in transactions that have a non-currency as
txn commodity, which is what the multi-currency register tried to avoid hard.
Now by using account_or_default_currency, the currency choosing policy from
the register is available in the other places where new transactions are
created, hence we better use that here.
