Turn off test users for UNC e-bike

@mattwigway FYI, I just turned off test users from the dashboard since it looks like your study has started. This means that your test data will no longer count towards the public dashboard metrics, and will not appear on the admin dashboard by default.

On the admin dashboard, you can still see the test users if you change the filters.

Feel free to change it back if you don't like this, but I'm just curious about the results... 😄
