[FEATURE] Call autologin also if user already confirmed

You can set autologinPostConfirmation so an user is
automaticly logged-in after confirming his account change.
But if the account is not disabled by the last change the
autologin will not work.

Move the autologin down so it is also called when user
already logged in.
