chore: Resolve flaky spec for Contact country sorting (#10810)

We have been encountering errors in the community pipeline for the
contacts sort by country spec. Upon investigation, it was discovered
that the spec assumes the country code is used for sorting. However, the
sorting actually relies on the country attribute.

The payload from a previous spec run indicates that none of the contact
objects include the country attribute. This fix addresses the issue by
aligning the spec with the actual implementation logic.

Here’s an example payload from the previous spec run for reference:
