 As `\WP_REST_Attachments_Controller::update_item()` calls
 `\WP_REST_Posts_Controller::update_item()`, this causes the
 `rest_insert_attachment` and `rest_after_insert_attachment` hooks to be
 fired twice on update requests, once in each controller class.

 Creating as item isn't affected as the attachment controller does not call
 the parent class.

 `rest_after_insert_attachment` is new for version 5.0
 `rest_insert_attachment` is from a previous version of WP
