Greeklish-permalink < 3.5 - Unauthenticated Post Slug Update

Proof of Concept

1. Create a post with the name "Νέα ανάρτηση".

2. Visit the post and notice that the permalink uses the Greek characters.

3. In an unauthenticated browser session, run the following code: fetch('/wp-admin/admin-ajax.php?action=cyrtrans_ajax_old', {method: 'POST'})

4. Visit the post again, and notice that the permalink now uses Latin characters.
