[PATCH] Some fixes to the Emergency Access PR

- Changed the date of the migration folders to be from this date.
- Removed a lot is_email_domain_allowed checks.
  This check only needs to be done during the invite it self, else
everything else will fail even if a user has an account created via the
/admin interface which bypasses that specific check! Also, the check was
at the wrong place anyway's, since it would only not send out an e-mail,
but would still have allowed an not allowed domain to be used when
e-mail would have been disabled. While that check always works, even if
sending e-mails is disasbled.
- Added an extra allowed route during password/key-rotation change which
updates/checks the public-key afterwards.
- A small change with some `Some` and `None` orders.
- Change the new invite object to only generate the UTC time once, since
it could be possible that there will be a second difference, and we only
need to call it just once.
