[FIX] l10n_it_edi: Mismatching IdCodice

When codice fiscale is not the same as the partita IVA, the template was
utilising the wrong value for IdCodice in <IdTrasmittente>. It should
use the value of codice fiscale, and if it's not found, then use the vat
value (e.g. when it's not an Italian company).
