Changes:
* Rename the somewhat awkwardly named "popups_core" Cucumber feature and
its accompanying step definitions to "previews".
* Remove as many references to Popups and HoverCards as possible.
* Use language consistent with the QUnit unit and integration tests and
documentation, e.g. the user dwells on a link.
* Remove settings-related step definitions from the previews step
definitions.

The Hovercards checkbox on the beta preferences page doesn't have an ID
anymore. It has a name though, which is used from now on.
The regression was introduced in I8636f32330e23814ba3b4c0f5e22e55aaf77883e.

* Wait until the form submits successfully, verifying it
worked by testing for the notification toast.
* Drop sleep statements where possible - instead use when_present
Use one when asserting something doesn't show to avoid false positives
* Allow more time for the hovercard to show (5s) - API requests might take
longer than default time.
* Assert popups JavaScript loads before continuing with test. This
helped trap a bug in testing and will be useful for future.
