Lab "actionLink" should be fixed or removed.

The app used to have support for opening a link directly to a place to schedule an appointment with a lab. The API has changed a bit since then.

`webPermalink` could be used to restore the functionality. There is not a dynamic prompt anymore it seems.

POC here: https://github.com/insidegui/WWDC/compare/master...ah/action-link-label
