Prevent guest user account creation from triggering anything

[yscik]

• Investigate what can happen when creating an user. For example, emails sent to the site author, scheduled marketing emails. Consider popular plugins that act upon user account creation.
• Figure out a way to trigger those actions.

Actions to prevent for guest/preview users

• [x] Sensei emails, eg Your student has started a course → #6358
• [x] ~WooCommerce~ → New account email is only sent when created from their checkout page
• [x] ~WordPress 'New User Registration'~ → Not sent
• [x] MailPoet - List 'WordPress Users' automatically contains new WP users → Workaround in #6358
• [x] MailPoet - 'Wordpress user registers' hook for transactional emails → Disabling user_register hook in #6358

@yscik It appears that guest users are still automatically added to the MailPoet 'WordPress Users' list. Reported in 9496914-zd-a8c and confirmed on my test site.
