Repair AccountingTransaction_roundDebitCredit: this script should round debit /

credit on created line (and adjust cents on the last line if needed, and if the 
difference is not too big, not to hide error in the configuration).
Enable AccountingTransaction_roundDebitCredit to be called on generated invoices.

This should fix testAccountingRules
