Parameterize test function with same name get mixed

[eleanorjboyd]

with "python.experiments.optInto": ["pythonTestAdapter"], to enable the re-write. If I have the following structure

test_a.py
-- test_class (where this is a parameterized test class)
test_b.py
-- test_class (where this is a parameterized test class)

the test cases in file_a for test_class will also appear in test_class in file_b on the test explorer.
