Serialiser_Engine: GenericTypeDefinition classes don't deserialise properly if different parameters present

[adecler]

Description:

Take for example the case of public class Tree<T> in BH.oM.Data.Collections

The problem for Tree is that the type is simply stored as Tree'1 without containing the Generic types. This is because the class itself is a GenericTypeDefinition (i.e. uses <T> in the class definition). So trees are deserialisiing properly as long as there is only one type of tree being deserialise. As soon as there is more than one, FromJson fails:

Here's another example easier to reproduce:

If I would rerun the FromJson of the LibraryTree, it would then give me a CustomObject
