To ensure that tests that modify cookies but don't finish cleanly don't leave cookie values that interfere with subsequent tests, we need to clear the cookie storage in between each test that's run.

Testing: Can't test the test runner, just have to watch the patterns in our test runs.

This definitely seems like it is worth a shot. I notice that the code for clearing cookies does not wait synchronously for the clear to complete. This could also add some intermittency to the operation.

Actually I don't think this will.do what I expected. I didn't realize this would only clear the cookies for the current origin of the document in the frame that is active. I think we want a custom command that will clear the entire cookie store instead.

I'm going to run a bunch of try jobs and see if any cookie tests appear in the list of known intermittents (ie. they're not fixed by this).
