Original issue's description:
> [Telemetry] Move some tests from page_runner_unittest to user_story_runner_unittest.
>
> These tests test logic of user_story_runner hence they should be moved to
> user_story_runner. In addition, the new tests use fake shared_user_story_state
> allows faster cycle time.
>
> Rename page_runner_unittest --> page_run_end_to_end_tests.
