test_results.py reference to file path

Lines 15 to 20 in 53f9575

	@pytest.fixture(scope="module",
	params=["test", "valid"])
	def prepared_data(request):
	data_path = Path("testing/data/bkw")
	exp_path = Path("testing/exp/19/")

This appears to reference a file path that may not exist since testing/ is explicitly in .gitignore. These tests could fail machine because of the lack of this file or worse be referencing some other unrelated experiment.

I would like to instead make reference to a test fixture here. Additionally I notice that there's a Corpus constructed from a pickle file, this is something we could potentially add in as a file into version control but I'm a bit concerned about adding in pickle files like that in general.

Looking at the test_results.py test file has given me more insight into what's happening. I think we can get good test coverage of results.py with a combination of mocks by extracting the results from a test run, I don't think we need a full Corpus object here because we aren't really using it aside from extracting utterance and label info.
