[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:
{{{
