[FIX] account: missing translation

- Install a second language, e.g. French
- Set Parter A language to French
- Create an invoice for A with a date due in the past
- On the partner form view, print the 'Due Payments'

The body of the letter is not translated in French.

Something quite weird appears:
- The corresponding string is exported in the `stock` module
- It is linked to the demo data `stock.res_company_1`, which corresponds
  to 'My Company, Chicago'.

Therefore, the translation cannot be found by the corresponding query
generated in `_generate_translated_field` and `_read_from_database`:
```
SELECT "res_company"."id" as "id",COALESCE("res_company__overdue_msg"."value", "res_company"."overdue_msg") as "overdue_msg" FROM "res_company" LEFT JOIN
                (SELECT DISTINCT ON (res_id) res_id, value
                 FROM "ir_translation"
                 WHERE name='res.company,overdue_msg' AND lang='fr_BE' AND value!=''
                 ORDER BY res_id, id DESC)
             as "res_company__overdue_msg" ON ("res_company"."id" = "res_company__overdue_msg"."res_id")
                        WHERE "res_company".id = 1  ORDER BY "res_company"."sequence" ,"res_company"."name"
```

Indeed, `res_company.id` is 1, while `res_company__overdue_msg.res_id`
is 3.

The root cause has been solved in v11, to we only export the necessary
term.
