test: more consistent test for findjsobjects -d (Sample Event Press Release Template)

findjsobjects -d test relies on how the hidden-class it tests is built. Zlib is a builtin from Node.js, therefore we cannot be sure about the order attributes are assigned to the class, making its hidden-class unpredictable. Using a class from our fixtures (in this case, Class) makes the test more predictable across Node.js versions and across multiple Operating Systems.
