Steps
-----
1. Have GeoIP enabled/mocked;
2. have at least 2 pricelists available in eCommerce;
3. have all pricelists restricted to a certain country group;
4. have the 1st pricelist be incompatible w/ the current GeoIP location;
5. open a cart as a public user;
6. check pricelist in back-end (should be correct);
7. go to "Sign In" & create a new portal account without address;
8. check pricelist in back-end (should still be correct);
9. go back to cart with portal account;
10. check pricelist in back-end.

Issue
-----
The first pricelist is assigned to the order, which shouldn't be compatibly with the partner's current GeoIP location.

Cause
-----
The pricelist is recomputed on changing the `partner_id` on a sale order. Commit 6504c0624b990 added a check on the `country_code` context value when retrieving the `property_product_pricelist` for a partner. This context value is currently not getting added during `_compute_pricelist_id`.

Because all pricelists are restricted to a country group, when the pricelist gets recomputed on `partner_id` change, there's no location-independent pricelist to fall back on, which is why the first pricelist is used regardless of country restrictions.

Solution
--------
Add a `_compute_pricelist_id` override which adds the current GeoIP country code to the context when computing the field for website orders.
