server success, don't remove attr on keyup

same as previous edit, don't remove attribute

first time field is validated at the server, server returns null message so newer code using inline err msg. works good.

then when editing input element value, on keyup event, attr holding the inline err msg is removed, and when server returns validation error with no message, the err displayed to user is blank, since the inline err msg has been removed previously.
