Introduced in c959edc, tasks with adaptivity would be reset when pressing continue, which makes sense in case the user arrives at the same task again.
Then later in 55638e2, we introduced reporting (.getXAPIData()) which is called once the task is finished.
The problem: All the tasks with adaptivity have been reset and no longer have any response when the attempt is submitted. I.e. it looks like the user didn't answer them.
1. Suggestion: We could aggregate the xAPI events as they occur instead of generating them on completion.
