### Godot version

v4.0.beta.custom_build [1d14c054a]

### System information

Kubuntu 22.10

### Issue description

Regression in master (in beta 10 the following script works correctly).

### Steps to reproduce

```gdscript
@tool
extends EditorScript

func wait(time: float) -> void:
    await get_editor_interface().get_tree().create_timer(time).timeout

func _run() -> void:
    reference()
    # Error: Cannot get return value of call to "wait()" because it returns "void".
    await wait(1.0)
    print("Test")
    unreference()
```
