Let users who didn't have emails to add emails
There are many people in my instance that did not write down emails when they signed up. Since account backups require users to have emails, users who didn't have emails will not be able to get their backups. Users can change email when they don't want to use their old email addresses, and I suggest we let them add new emails if they had left the email line blank. If pleroma already made it possible, please tell me how to do it. Thank you.
