This addresses #11627 by completing the documentation without changing the behavior. Some basic unit tests are added on ListView to ensure this won't change unintentionnally. That means a ListView widget with an empty provider and `showOnEmpty=true` will still display an empty element (by default, an empty "div.list-view").
