REST API: Expose old slugs

Expose the old slugs for all posts including custom post types in the REST API.

For example, when building a React-powered app using the WordPress REST API the old slugs are required so that users can be automatically redirected if they clicked on an old link.

To expose the old slugs I created a small plugin (see below):

add_action( 'rest_api_init', 'expose_old_slugs_in_api' );
function expose_old_slugs_in_api() {
  $post_types = get_post_types( array( 'show_in_rest' => true, 'show_in_nav_menus' => true ) ) ;

  $args = array(
    'get_callback' => 'get_old_slugs_for_api', 
    'schema' => null
  foreach ($post_types as $type) {    
    register_rest_field( $type, 'old_slugs', $args );
function get_old_slugs_for_api( $object ) {
  //get the id of the post object array
  $post_id = $object['id'];

  //return the post meta
  return get_post_meta( $post_id, '_wp_old_slug' );

I see no reason not to add this, so long as it's only available in the edit context.

I see the PR considers and edits unit tests, should we remove the needs-unit-tests tag?
