### 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()
```

### Minimal reproduction project

N/A
for (GDScriptParser::ClassNode *script_class : script_classes) {
				if (script_class->has_member(name)) {
					resolve_class_member(script_class, name, p_identifier);
					GDScriptParser::ClassNode::Member member = script_class->get_member(name);
					switch (member.type) {
						case GDScriptParser::ClassNode::Member::CONSTANT:
							
							p_identifier->set_datatype(member.get_datatype());
							p_identifier->is_constant = true;
							p_identifier->reduced_value = member.constant->initializer->reduced_value;
							return;
						case GDScriptParser::ClassNode::Member::ENUM_VALUE:
							p_identifier->set_datatype(member.get_datatype());
							p_identifier->is_constant = true;

							return;
						case GDScriptParser::ClassNode::Member::ENUM:
							p_identifier->set_datatype(member.get_datatype());
							p_identifier->is_constant = true;
							p_identifier->reduced_value = member.m_enum->dictionary;
							return;
						case GDScriptParser::ClassNode::Member::CLASS:
