BH.Upgrader.Base.Upgrader.GetMethodKey yields ambiguous results for methods with out collection parameters

[pawelbaran]

Description:

I have just noticed that BH.Upgrader.Base.Upgrader.GetMethodKey query called against a method with out param of collection type returns ambiguous results such as BH.Engine.Geometry.Query.PlaneIntersections(BH.oM.Geometry.NurbsCurve, BH.oM.Geometry.Plane, System.Collections.Generic.List, System.Double). On top of that, the format is slightly different (missing ``1&`) compared to what I reported under BHoM/BHoM_Engine#3384.
