Fixed the problem where lonstudentassessment would not update after the
data had been downloaded once, even though the student had done more
work. Now it updates properly. Simply set the value to false instead
of checking to see if it was defined, since I define it if it true. I
noticed the columns getting off a little now, so I will look at it next
