Pytest-azurepipelines is trying to publish test results even before the test-output.xml file is created.

We are running pytests using the following command:

```
python3 -m pytest -s --doctest-modules --junitxml=qa_integration_cli.xml --cov=. --cov-report=xml ./program.py --no-coverage-upload \
```

During the pipeline run, we see that the plugin is trying to publish test results even before the test-output.xml file is created.
We keep getting warnings as a result of this.

Azure Pipeline team mentioned that this seems like issue with plugin pytest-azurepipelines.
