Let's install base_vat_autocomplete and base_address_extended
When creating a contact with a VAT number, the street was not
formated by the autocomplete in a correct way because the function checkVat all the time
returns the street with the following format: '%(street_name)s, %(street_number)s/%(street_number2)s'
and this function doesn't take the street format of the country into account.
So the function _split_street tried to split the street into street_name, street_number, street_number2 with the
street_format of the partner but the street was not well formated by checkVat.
