### Godot version

v4.0.beta.custom_build [fab9926a9]

### System information

Fedora 37

### Issue description

When creating a new inherited scene, saving the scene (for example with Ctrl+S) defaults to overwriting the scene being inherited, instead of prompting for a location to save to.

### Steps to reproduce

1. Create a new inherited scene
2. Press Ctrl+S

If the scene being inherited is imported (for example from a glTF), an error displays. If the inherited scene is a .tscn or .scn, it gets overridden by an inherited scene that tries to inherit itself, which is impossible and thus corrupt.

### Minimal reproduction project

Node *scene = editor_data.get_edited_scene_root(p_idx);
	if (!scene) {
		return;
	}
	String path = EditorPaths::get_singleton()->get_project_settings_dir().path_join(p_file.get_file() + "-editstate-" + p_file.md5_text() + ".cfg");
	Ref<ConfigFile> cf;
	cf.instantiate();
	Dictionary md;
	if (p_idx < 0 || editor_data.get_edited_scene() == p_idx) {
		md = editor_data.get_editor_states();
	} else {
		md = editor_data.get_scene_editor_states(p_idx);
	}
	List<Variant> keys;
	md.get_key_list(&keys);
	for (const Variant &E : keys) {
		cf->set_value("editor_states", E, md[E]);
	}
	Error err = cf->save(path);
	ERR_FAIL_COND_MSG(err != OK, "Cannot save config file to '" + path + "'.");
