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

#### 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 https://github.com/BHoM/BHoM_Engine/issues/3384.
