Github Actions: Use poetry + Coverage without breaking codecov

[lhl2617]

The right way to set up a poetry CI env is shown in #14 in .github/workflows/unittest.yml.

The below was tried for .github/workflows/unittest.yml but does not work due to Codecov failures.

name: Test and collect coverage
on: [push, pull_request]
jobs:
  run:
    runs-on: ubuntu-latest
    env:
      OS: ubuntu-latest
      PYTHON: "3.9"
    steps:
      - uses: actions/checkout@v2
        with:
          fetch-depth: 2
      - name: Setup Python
        uses: actions/setup-python@master
        with:
          python-version: 3.9
      - name: Setup Poetry
        uses: abatilo/[email protected]
        with:
          poetry-version: 1.1.4
      - name: Install dependencies
        run: poetry install
      - name: Collect coverage
        run: poetry run coverage run -m unittest
      - name: Upload Coverage to Codecov
        uses: codecov/codecov-action@v1
        with:
          verbose: true

The codecov step apparently passes, but the codecov website showed that it failed without much reason.

My guess is that the previous workflow.yml file has a faulty .env in which the env entry gives 3.9 for python, but the Setup Python step uses a 3.7 version instead. This makes the env mismatch problem persist, but that doesn't make sense to be honest.

The difference in running the test poetry run coverage run -m unittest vs. coverage run -m unittest may be an issue as well, but running test -f .coverage for the former does not fail.
