Summary: Update the eden_repo_test decorator so that it no longer automatically adds `EdenRepoTestBase` as a parent class. Individual test classes still specify `EdenRepoTest` as their parent now. This enables `mypy` to correctly figure out that the individual test classes derive from `unittest.TestCase`. This basically does the same thing as D6268258 for the top-level integration tests.
