[New Quizzes] Detect Multiple Sessions

[KKNIGHTON]

Problem statement:

An instructor has asked why the "detect multiple sessions" couldn't be auto-applied to every quiz instead of instructors having to go into each quiz and making sure it is turned on.

Proposed solution:

In order to save instructors time and in case they forget to check the box, the "detect multiple sessions" button should be auto-applied to every quiz, ones already created and ones that will be created.
