WordPressVIPMinimum: alternative fix for the failing ruleset test

Follow up on the original fix.

* Now, instead of having a condition for the PHP 5 parse error, the `$this` variable has been renamed to `$stdClass`.
* And the PHP 7 parse error on line 7 has been changed to a syntax which is a parse error on both PHP 5 as well as 7.
