[issue17066] Fix test discovery for test_robotparser.py

[Zachary Ware]

New submission from Zachary Ware:

Here's a fix for test_robotparser.py.  With this patch, the command 'python -m unittest discover Lib/test/ "test_*.py"' can actually be run--before the patch, test_robotparser's unique TestCase subclass causes unexpected errors for discovery.
