[FIX] account_tax_cash_basis: raise if no account

Since the account is a mandatory field, we raise an clear error is no
account is defined.

This is necessary when running an automatic reconciliation on the POS.
The POS uses a try/except to avoid any error, but in the case of an SQL
error, the cursor is invalidated, so the transaction fails.
