    ListViewTestModule: Refactor Model class to inherit from BaseListModel
    
    Mono 3.6.0 was warning about the Cleared and Reloaded event not being
    used, so instead of adding a dummy implementation of OnCleared and
    OnReloaded, we inherit from BaseListModel. This allows to make the Model
    class even simpler.
