Problem analysis was failing for Davidson Next courses. "student_answers" did not appear in some problem states. Note yet 100% sure which problems, but my feeling is that the new "problem-builder" package that allows for free text entry is the culprit. For now, this PR allows the problem_analysis to continue for those states that do contain "student_answers".
