JS objects instead of HBS in tests

[anehx]

Currently we have some tests notating objects in HBS:

{{cf-field/input
  field=(hash
    question=(hash
      checkboxOptions=(hash
        edges=(array
          (hash node=(hash slug="option-1"))
        )
      )
      __typename="CheckboxQuestion"
    )
    answer=(hash
      listValue=(array "option-1")
    )
  )
}}

We should do this in JS instead.
