  Demo mode results in 5XX
  ## Description
  <!-- A clear and concise description of what the bug is. -->
  
  Mathesar is broken (as of 0.1.4) for Demo Mode. It doesn't load, and just says "Server Error (500)" instead.
  
  ## Expected behavior
  <!-- A clear and concise description of what you expected to happen. -->
  
  Demo mode should work.
  
  ## To Reproduce
  <!-- How can we recreate this bug? Please try to provide a Minimal, Complete, and Verifiable (http://stackoverflow.com/help/mcve) example if code-related. -->
  
  Change the `.env` file according to the comment to use the demo mode settings, try to build and start mathesar (dev environment is fine)
