CORE-481 change auto generate checkbox from autogenerate objectives into controls.
@bmomberger-reciprocity I've already merged this, but now I noticed that is says `this Objective has...` when you create controls. I think we should at least write `this objective has...` (lowercase objective), but a bigger rewording to incorporate controls would probably be better, do you agree?
