Generate JavaScript object for a CacheEntity created for an Interface

[canhorn]

To the default constructor for Interfaces that have a CachedEntity create should create a default object in the JavaScript layer.
This will make it so the cached entity can be easily created and referenced.

public InterfacedCachedEntity()
{
    var entity = EventHorizonBlazorInterop.New(new string[] { "Object" }, null);
    ___guid = entity.___guid;
}
