[FIX] portal: fix submitting /my/account when can't edit VAT

Since 1be6866b15, when VAT can't be
edited, the country_id select field is disabled.
Disabled fields aren't submitted in the POST query, which causes an
error `Some required fields are empty`, with the Country field being
highlighted even if a value is selected.

With this commit, when the user cannot edit their country, the value is
forced into the POST data so that it is found.
