If a scenario is skipped entirely, there's no SauceLabs session and the API call responsible for annotating the session fails. This only applies to <= 0.4.x versions of MW-Selenium. The teardown method in 1.x should work as it iterates over all open browser sessions in the factory instead of assuming the state of a `@browser` instance variable.
