Noty errors don't show up on user save fails anymore

More of a proposition really: I didn't like how Noty errors popped up when I tried to generate user name conflicts on the account settings page. Users don't need it because a fancy error shows up next to the offending field. There might be other cases where you think it IS desirable for users, but I couldn't find any.
