Polygon entities are classifying 3D Tiles by default

See original GitHub issue

Any polygon created with the entity API is classifying 3D Tiles by default, but it should instead appear underneath.

@bagnell could you take a look at this?

@lilleyse everything defaults to being a ground primitive through the Entity API unless you specify height. This is so it contours to terrain by default.
