[FIX] account: print invoice

- Create a user A with group `group_sale_salesman` but no Accounting &
  Finance group set
- Create and validate a SO, create the invoice
- With another user B, pay the invoice
- Print the "Invoices" with A

An access error occurs.

The error is due to user A not having the rights to see the payments.

We set a group on the corresponding report to avoid a user without
proper rights to print it.
