When we view a course and back to dashboard, the result in the Course overview block is not correct if we sort by "Last accessed".

Steps to reproduce:

1. Using the app, log in to as a student.
2. Sort the course overview by Last Accessed.
3. View a course that is not at the top of the list.
4. Go back to the Dashboard page.
5. Sort the Course overview block by Course name.
6. Sort the Course overview block by Last Accessed.

Actual: The list of courses is in the same order. You must pull-to-refresh to update the order of the list.

Expected: The course that you viewed is now at the top of the list when we sort by "Last accessed"
