Sidebar Duplicates

[rileyma]

Description of Issue

When creating a course, if you add yourself as a professor, the course appear twice in the sidebar. These don't appear to be two separate entries in the database, rather, the UI is displaying the same entry twice

How to Replicate the Bug

• Boot up front end and back end of the system locally
• Navigate to your localhost that runs Compile.io
• Sign in to the system
• Using the sidebar, create a new course
• When creating the course, add yourself as a professor. This is the same name you used to login.
• Notice that once the system redirects you back to the main page, you can see your newly created course twice in the side bar

Acceptance Criteria

• [x] Replicate the bug
• [x] Fix the bug; Make it so no duplicates appear in the sidebar UI
• [x] Create a PR asking others to attempt to replicate the bug on their machines, ensuring the fix
