After account verification, user isn't redirected back to login page

I'm not sure whether this is intended, but it would be nice if the user would be redirected to the login page after say ~3-4 seconds.

Because there is no way to check what message the back-end returns here
(if the message is successful or not), let's instead add a button to the log-in page.
