Message:

Tests: Resolve WP_Query test failures on MariaDB due to indeterminate sort order.

[54768] added a few tests to verify that caching within WP_Query is bypassed when the SELECT clause has been modified via a filter, to avoid cache key collisions and the returning of incomplete or unexpected results.

However, creating several posts with the same date/time fields can result in inconsistent sort ordering between MySQL and MariaDB, as each engine refines the order further using a different index.

This commit aims to stabilize the tests by using assertEqualSets() instead of assertEquals(), since testing the order is out of their scope. Includes removing array_unshift() and array_reverse() calls as no longer needed.

This resolves a few test failures on MariaDB along the lines of:

Tests_Query_FieldsClause::test_should_limit_fields_to_id_and_parent_subset
Posts property for first query is not of expected form.
Failed asserting that two arrays are equal.
