Tests: Remove use of assertArraySubset() in `Test_WP_Widget_Media::…

…test_constructor()`.

The `assertArraySubset()` method has been deprecated in PHPUnit 8 and removed in PHPUnit 9.

This replaces the assertions with looping through the array and testing both the key and the value individually.

* sebastianbergmann/phpunit#3494

Note: There is a polyfill package available for the removed assertion: `dms/phpunit-arraysubset-asserts`, but as the assertion was only used in this one test method, adding this seems redundant.

Follow-up to [51559-51568].

Props jrf.
