As a Wikimedia logged in user, I would like quickSurvey to provide me the ability to go back and change my previous question selected.
AC:
- The UI will not show a "back" button in the first question
- The UI will show a "back" button from the second question onward
- When the user clicks the back button the previous question will show
- When the previous question is shown, this will be "prefilled" with the user input
- The story will be unit tested
