Fix for bugs in the Conditional Questions functionality:

     - In case of conditional question with checkbox answers the removed
       questions were not being removed from view, nor was the answer to
    these questions (which persisted in the db.

    Changes:
    - Fixed the broken functionality in the method remove_answers_list in
      app/helpers/conditions_helper.rb.
    - Removed and destroyed the answers of the removed questions.
    - Added more tests for Conditional Questions functionality.
