Make sure we render error messages on `/profile` in an alert-banner instead of a notice banner
When POST-ing invalid data when updating the user profile, we render the error messages in the wrong banner: ![Screen_Shot_2018-07-30_at_15.29.35](/uploads/3af3666ee15d4332e94683a11ea541da/Screen_Shot_2018-07-30_at_15.29.35.png) This should be an alert banner like we have for the other setting pages.
