### Godot version

4.0.beta10.mono.official

### System information

Windows 11

### Issue description

After registering a C# Script with Autoload and trying to connect to a signal using the `Signal.connect` method (`Singleton.Signal.connect(xxx)`) fails with `Invalid get index 'Signal' (on base: 'Node (Singleton.cs)'). But with `Object.connect` it works.

### Steps to reproduce

- Create a C# class script with a Signal named `Signal` (could be any other).
- Register it with Autoload with the name `Singleton` (could be any other).
- Create a GDScript script and try to connect the Singleton's signal using `Singleton.Signal.connect(xxx)`
- When running the project it fails with `Invalid get index 'Sample' (on base: 'Node (Singleton.cs)').`
