Issue description

Part of the process of reloading assemblies involves deserializing delgates - presumably as a way to recover editor state. When that's happening, if a 0-parameter method has overloads, attempts to uniquely acquire that method with System.Type.GetMethod will throw System.Reflection.AmbiguousMatchException: Ambiguous match found.

Steps to reproduce

In the minimal repro project:

1. Compile C# code.
2. Ensure the GetMethodRepro plugin is enabled.
3. Restart Godot and open the project.
4. Make any change to the non-plugin code Anything.cs.
5. Recompile while the editor is still running.
