Sign out button unexpectedly links to localhost

When attempting to sign out of TrackIT, the browser is directed to the localhost, and not to the TrackIT homepage.

**To Reproduce**
Steps to reproduce the behavior:
1. Navigate to "https://trackit.acmutd.co" in a browser
2. Click the black "sign in with acm" button near the upper center of the page
3. A login page should appear. For testing, I signed in using Google. Follow the. necessary steps to complete sign in.
4. Once sign in is complete, you should be placed back at the TrackIT workshop page.
5. Click the "Home" button in the website's navigation bar
6. Click the "Sign Out" button at the right of the website's navigation bar.
7. Observe that the browser will attempt to navigate to "http://localhost:3000"

**Expected behavior**
After signing into an account, then clicking the "Sign Out" button, I expect the website to return to the TrackIT homepage (https://trackit.acmutd.co)
