[8.0] Invoice language error

[daviddiz]

When we import partners from Magento, we could create from one to four res.partners records in odoo depending if the partner is company and if the billing and shipping address are different.
The main partner language is the language of the storeview but the language of the contacts or addresses related to that main partner aren't the same.

If we import a sale.order from that partner to odoo, the sale.order report will be in the correct language, but if we create an invoice from that sale.order the language is taken from the res.partner address where is not set correctly. Then the invoice report will be in an incorrect language.

The solution will be set the language of the main partner to its addresses.
