  <issue>
  Flatpages and Redirects broken when using ASGI
  Examples:
  
  - https://grand-challenge.org/about/ (flatpage, exists)
  - https://grand-challenge.org/about (should redirect to https://grand-challenge.org/about/)
  - https://parse2022.grand-challenge.org/Participation (should redirect to https://parse2022.grand-challenge.org/Participation/)
  - https://parse2022.grand-challenge.org/gfsdfgdfdsg (should redirect to https://parse2022.grand-challenge.org/gfsdfgdfdsg/, which should 404).
  
  Error occurs in the clickjacking middleware:
