Message not showing up

The message that should be shown to the user was not working properly.

I added this line

    $_SESSION['messages']['status'] = array_values($_SESSION['messages']['status']);

Just below (123)

    unset($_SESSION['messages']['status'][$position]);

The line re-indexes the messages form "0"

Problem is if we unset the message in index 0, thing don't work properly form then on and any remaining messages are not printed.

Marking as major as this causes plenty of users not to look for the activation email.
