It doesn't add much value in terms of testing
(can't see how we'd ever mess up the "Help" menu entry),
and it relies on the availability of an external resource
(userhelp.ss.org), making the tests more brittle.
It also breaks the feature following this one, because
somehow Behat doesn't reset the browser session, so
subsequent logins fail because a login still exists.
Too many clashes with other steps otherwise,
e.g. with 'And the preview contains "You can fill"'.
Also removed some duplicated code no longer necessary
because we use inheritance rather than composition
They can be unpublished through an explicit step.
Extending from base FeatureContext in order to easily
share the same FixtureFactory but still add new blueprints to it.
