    Mock swiftclient's functions in tests

    swiftclient changed their code so if the chuck size is greater than
    zero it will return a generator otherwise it will return the response.
    Which would be the object you are looking for. This causes our tests
    to fail since they are always expecting the response instead of a
    generator.
