The Run tests for Input/Output Tests doesn't produce an actual output when a SQL (running main.sql) project

Bug description:
After getting the message, “We’ve upgraded your project!” (migrating my Repl to Nix), I can no longer run tests under Input/Output Tests when running a SQL project.

Expected vs Current Behavior:
Expected: Be able to compare an expected and actual output and see the difference. The tests passed.
Current: The expected output is still there. But, no actual output is produced; it’s blank. Difference is also blank. The test fails.

Steps to reproduce:

  1. Click Test under Tools.
  2. Click Run tests under Input/Output Tests
  3. The result is ‘Failed’.
  4. Click the Results button.
  5. Confirm Actual output is blank, and Different is blank.
