Hooks/PreGetPosts: add support for hook-ins using short arrays

As VIPCS is currently using WPCS 2.x, we can use the WPCS `Sniff::find_array_open_close()` method to get the opener/closer for an array independently of the type of array (long/short).

Once VIPCS implements PHPCSUtils, this method call should be swopped out for the PHPCSUtils `Arrays::getOpenClose()` method.

Addresses #358 for the `PreGetPosts` sniff.

Includes unit tests.
