samigo: Incorrect tab display when accessing student submission via User Activity Report

If you access a student's submission by clicking a link in the User Activity Report, the links at the top of the page are styled incorrectly and Questions link is missing.

Testing Steps:

1. In a site with at least one student, create a quiz.
2. As a student, take the quiz.
3. Log in as instructor and go to Tests & Quizzes > User Activity Report
4. Select student.
5. Select submission.
   • If Issue Present: The tabs, Submission Status, Total Scores, etc. are styled incorrectly (as links - inconsistent with views in other Scores screens) and the Questions tab is missing completely.
     
6. To see correct display, go to Published Copies > Scores > click student's name.
