New Django test feature: can't find '__main__' module

Type: Bug

Hello team vscode-python, @eleanorjboyd ,

I finally had some time to try the new Django testing in VSCode. Unfortunately, I couldn't get it to work.

Here the log output:

My settings.json:

{
  "editor.codeActionsOnSave": {
    "source.organizeImports": "explicit"
  },
  "editor.formatOnSave": true,
  "editor.rulers": [100],
  "isort.args": ["--profile", "black"],
  "notebook.codeActionsOnSave": {
    "source.organizeImports": "explicit"
  },
  "notebook.formatOnSave.enabled": true,
  "python.envFile": "${workspaceFolder}/.env.local",
  "python.experiments.optInto": ["pythonTestAdapter"],
  "python.testing.pytestEnabled": false,
  "python.testing.unittestArgs": [],
  "python.testing.unittestEnabled": true
}

My launch.json:

{
  // Use IntelliSense to learn about possible attributes.
  // Hover to view descriptions of existing attributes.
  // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Python Debugger: Django",
      "type": "debugpy",
      "request": "launch",
      "args": ["runserver", "0.0.0.0:8000"],
      "django": true,
      "autoStartBrowser": true,
      "program": "${workspaceFolder}/src/manage.py"
    }
  ]
}

cd src && python manage.py test works well in the VS code terminal.

Since I wasn't sure that the problem wasn't due to the fact that I had a src subdirectory in my project, I redid the test with a new Django project, and I have the same issue.
