tests/test_parse_qs.py: remove unused test to make mypy ok

mypy was complaining about this test which has been already skipped
unconditionally as it was throwing deprecation warnings.

With werkzeug 3.0.0 this attribute is no longer defined so that makes mypy
to fail, and it was the easiest to remove the test case.
