[FIX] l10n_it_edi: downpayment document type selection fix

TD02 is the only document type in l10n_it_edi that requires
the invoice to be a downpayment, but this doesn't mean that
downpayments are limited to it.
The condition has been adapted to allow downpayments to fall
under the other document types cases.
