test: refactor async-hooks/test-httparser tests

My first contribution to open source.

By advice from Rich Trott I have modified both the test-httparser.request.js changing the string literal on line 22 and then also the file test-http.response.js removing unused arguments from the method. Pull request contains two commits.

Screenshot is attached of the tests that have all been passed.
