Fix issue with generating a single hardcopy test version.

  The $selected_set_id name was updated to be displayed, but was still
  being used as the set id parameter. This moves the display change to
  the line it is being used to ensure the set id parameter is unchanged.

  Fixes openwebwork#1930
