### 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

N/A
Ref<DirAccess> dir = DirAccess::create(DirAccess::ACCESS_FILESYSTEM);
	for (int i = 0; i < p_files.size(); i++) {
		String from = p_files[i];
		String to = to_path.path_join(from.get_file());
		if (dir->dir_exists(from)) {
			Vector<String> sub_files;
			Ref<DirAccess> sub_dir = DirAccess::open(from);
			sub_dir->list_dir_begin();
			String next_file = sub_dir->get_next();
			while (!next_file.is_empty()) {
				if (next_file == "." || next_file == "..") {
					next_file = sub_dir->get_next();
					continue;
				}
				sub_files.push_back(from.path_join(next_file));
				next_file = sub_dir->get_next();
			}
			if (!sub_files.is_empty()) {
				dir->make_dir(to);
				_add_dropped_files_recursive(sub_files, to);
			}
			continue;
		}
		dir->copy(from, to);
