[Telemetry] Move some tests from page_runner_unittest to user_story_runner_unittest.

[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.

This causes the exception to get printed twice.

Once here and once in results.AddValue.
