Crash in local CircleCI 2 run

[akx]

The codecov Python client crashes in a local CircleCI run (using the CircleCI 2 CLI), since not all of the environment variables it expects to be available are (even if the build is technically a CircleCI run).

This is admittedly a bit of a fringe use case, but it makes testing CircleCI flows locally harder.

I am seeing the same issue when executing circle ci locally.

Traceback (most recent call last):
  File "/home/circleci/repo/venv/bin/codecov", line 11, in <module>
    sys.exit(main())
  File "/home/circleci/repo/venv/lib/python3.7/site-packages/codecov/__init__.py", line 354, in main
    slug=os.getenv('CIRCLE_PROJECT_USERNAME') + "/" + os.getenv('CIRCLE_PROJECT_REPONAME'),
TypeError: unsupported operand type(s) for +: 'NoneType' and 'str'

Here is my relevant circle config:

        environment:
          CODECOV_TOKEN: 18a8804c-xxxx...
...
      - run:
          name: upload coverage report
          command: |
            . venv/bin/activate
            pip install codecov
            codecov -t "$CODECOV_TOKEN"

Running it locally using circleci local execute

It runs fine on circleci

I am experiencing the same issue running it locally. I tried to pass in the env variable CIRCLE_PROJECT_REPONAME and able to reproduce the same error.
