New Semester Cookie Reset

[dfarooq610]

At the beginning of every semester, some folks are directed to the "No Courses" page even though they are in a course that is using the app. The issue is fixed when people clear their cookies. I believe it may be caused when the "defaultCourse" is set but does not match any of the new courses that the user has. Investigate what is causing this and how we can update their cookie so that they can login without hassle every new semester.

• Look into how we use local storage on the frontend
• Update local/session storage for a new course
