[FIX] l10n_nl_edi: fix traceback when posting an invoice

Steps to reproduce the error:

- Create a new company, set Netherlands as country and fill in the required info (street, zip, city, vat, kvk-number).
- Set a bank account on the company contact.
- Install NL chart of account on this company (Netherlands Accounting package).
- Create a test customer, and don't set any address or set a country not listed in EAS (https://docs.peppol.eu/poacc/billing/3.0/codelist/eas/).
- Create an invoice for this test customer and try to post it.

Before this commit, if a Dutch company had tried to create an invoice for a customer from a country not listed in the Electronic Address Scheme (EAS) codes, Odoo would have given them a traceback error.

Now the code checks if the customer is from an EAS country: if they are, the code renders the bis3 invoice template, if not a UserError is thrown explaining the problem.
