Reset task should remove files: #59
Description
Resetting a task should delete the file reference. This may happen when that task is restarted, or when a prior task is restarted in the same subworkflow and the follow-on tasks propagate to “not yet started”.
Approach: The Reset API calls TaskTrigger > Reset. For each task instance being reset (original or follow-on), set the value of the database field taskInstance.files to NULL.
Where on FE: FYI, on the FE, Reset Task is called from the pop-up menus on each task on the Assignment Status screen. (You don't need to know this to fix it in the BE.)
