[FIX] base_vat: only use VIES service for company VAT numbers

Some countries, such as Portugal, persons also have VAT-like tax
numbers, that can be used in invoices, just like company VAT numbers
can.

However, the VIES service does not work for these person VAT numbers,
only for companies.

This fix ensures that VIES validation is only used for companies.
