Qt Account confirmation email has old URL in it

In case no admins realized it, confirmation emails for new Qt Accounts have a digia.com link at the bottom

@gmabey :) I'll tell them. They have been so deep in work for the past three months, that they haven't probably had time to look.

Also this is the normal problem for people who make the systems, they have the first accounts and don't look again.
