Geometry_Engine: IPointAtParameter fails for Ellipses

[rolyhudson]

This works fine with other ICurves but fails for Ellipses.

Looks like the dynamic conversion converts the ellipse to arc?

- Error: The best overloaded method match for 'BH.Engine.Geometry.Query.PointAtParameter(BH.oM.Geometry.Arc, double)' has some invalid arguments
- Occured in  BH.Engine.Geometry.Query.IPointAtParameter(ICurve curve, Double t)
     called from BH.UI.Templates.MethodCaller.Run(Object[] inputs)
- Are you sure you have the correct type of inputs? Check their description for more details.
