Fix CheckboxWithLabel integration with Form

[luacmartins]

Problem

While refactoring AddDebitCard to use our Form component, I noticed that CheckboxWithLabel only works when the shouldSaveDraft prop is passed.

Why is this important

The component should work with Form so it can be used in our refactors

Solution

Make it work without passing shouldSaveDraft

I'm focused on the NewDot API issues, but will get to this next.
