[BUG] Ignores whether there are errors when regisering

When a user is registering if they do not enter a valid email, username etc. and when there is a redirect_to value set in the url.
The registration page does not show the errors and the user is redirected to the page in the redirect_to alue.
This is because this code is wrong in CMInvitationCodesActivation.php:

if (!empty($_POST['redirect_to'])) {
            // if a redirect_to is set, honor it
            wp_safe_redirect($_POST['redirect_to']);
            exit();
        }

        // if there is an error already, let it do it's thing
        if ($errors->get_error_code())
            return $errors;

it should be:

// if there is an error already, let it do it's thing
        if ($errors->get_error_code())
            return $errors;

        if (!empty($_POST['redirect_to'])) {
            // if a redirect_to is set, honor it
            wp_safe_redirect($_POST['redirect_to']);
            exit();
        }

Also – great plugin once I fixed this!
