Fix `Unauthenticated` nested query test failures

Ensure the spected HTTP status code is included in
`metabase.query-processor-test.nested-queries-test` POSTs as when it
is not included our `retry` unauthenticated logic doesn't get
executed. Depending on the test order, the database and mock session
store might be out of sync and not retry authentication failures.

Fixes #7490
