🐛 [BUG]: Checkboxfield changes from uncontrolled to controlled in unit tests

[brandonlenz]

Current Behavior

First noticed here: #88 (comment)

During unit tests, the following output is shown, and it indicates a problem:

 Warning: A component is changing an uncontrolled input to be controlled. This is likely caused by the value changing from undefined to a defined value, which should not happen. Decide between using a controlled or uncontrolled input element for the lifetime of the component. More info: https://reactjs.org/link/controlled-components

This often happens when an uncontrolled input starts getting managed by something like a form library (RHF in this case). Can be as simple as not regisering the field initially. Sometimes it is more complicated and might be a bug within the component itself
