piecash._common.GncValidationError: Account 'Account<Income[USD]>' used in the transaction is a placeholder

From GNUCash documentation:

Placeholder accounts are used to create a hierarchy of accounts and normally do not have transactions or opening balances.

A transaction used a place holder account ('Account<Income[USD]>') which is illegal. This isn't caught until book.save() for whatever reason.

I simply need to update the translations.json to fix the issue.
