Register2: Improve commodity/currency handling: Try to always use account_or_default_currency lookup instead of code duplication.

The code for ensuring a commodity that is a currency was duplicated among
the file. This is now refactored into the reg_currency variable. Also, in
a non-currency register the currency is now taken from parent accounts or
the default currency, which matches the old register's policy but is different
from what register2 previously did.
