Crashes when Menu Data is empty

If the collection you pass to the Menu Data parameter is null or empty, you will get an exception like this

System.ArgumentNullException: Value cannot be null. (Parameter 'source')
   at System.Linq.ThrowHelper.ThrowArgumentNullException(ExceptionArgument argument)
   at System.Linq.Enumerable.ToList[TSource](IEnumerable`1 source)
   at Telerik.Blazor.Components.TelerikMenu`1.<BuildRenderTree>b__0_0(RenderTreeBuilder __builder2)

For the time being, an if-block around the menu is the way to avoid the error, like you would with standard loops over data rendering plain html elements.
