ClassDB::bind_method not properly casting Variant to Node

[WildRackoon]

I reproduced the error in this forum issue : https://godotforums.org/d/31691-how-to-bind-a-function-with-a-node-as-parameter

Methods using a Node as parameter works in Godot internal modules, but not when using godot-cpp in a GDExtension.

void MyClass::my_func(godot::Node *p_node) {
  // ...
} 

void MyClass::_bind_methods()
{
  godot::ClassDB::bind_method(godot::D_METHOD("my_func", "node"), &MyClass::my_func);
}

Outputs following Templates errors:

godot-cpp\include\godot_cpp/core/binder_common.hpp(89): error C2440: 'return': cannot convert from 'const godot::Variant' to 'T'
        with
        [
            T=godot::Node *
        ]

I can't figure how internal modules obtain this casting behaviour, any ideas ?

Probably this PR can help #950

The latest version does not seem to have this problem anymore.
