[BUG] Matrix rates: 'The country isn't available' exception because an incorrect scope is used

[YachYaroslav]

To Reproduce Steps to reproduce the behavior:

1. Prerequisites
   1. Having at least 2 websites (scopes) configured in Magento
   2. Each website has its own list of available countries. (E.g. site1 has only the Netherlands and Belgium, while site2 has only Germany).
   3. One of the websites domain is being used for accessing and using the admin area (e.g. site1).
2. Click on 'POSTNL' menu item in the admin navigation on the left.
3. Click on 'Matrix Rates'.
4. Add a new matrixrate (country: Germany, other values don't matter) for site2 (available countries in the configuration for site2 = [Germany]).
5. Visit 'Matrix Rates' again to overview the grid with the rates.

Expected result We see the list with the matrix rates created in our Magento installation.

Actual result We see the message 'The country isn't available', which is an exception thrown when calling (in Ui/Component/Matrix/Listing/Columns/Country.php):

$countryInfo       = $this->countryInformationAcquirer->getCountryInfo($value);

Workaround Enable the country for site1, because in getCountryInfo the website configuration of current admin store view (so website site1 and not site2) is used.

Or (rewrite the country name retrieval a bit differently). My own class example (<column name="website_id" class="BytesGuru\PostNL\Ui\Component\Matrix\Listing\Columns\Website"/>):

}

Note: we don't have the website_id available on the moment of \TIG\PostNL\Ui\Component\Matrix\Listing\Columns\Country::prepareDataSource execution, because it has been overwritten by its name for each row in \TIG\PostNL\Ui\Component\Matrix\Listing\Columns\Website::prepareDataSource. So the altering is required there as well or another method should be used for getting the full country name for each row.
