Fix twine upload
Running the new **invoke pypi** command to build and upload a release to PyPI fails in the very last step with the following error message:

```sh
Uploading distributions to https://pypi.python.org/pypi
Note: you are uploading to the old upload URL. It's recommended to use the new URL "https://upload.pypi.org/legacy/" or to leave the URL unspecified and allow twine to choose.
Uploading cmd2-0.9.0.post1-py3-none-any.whl

RedirectDetected: "https://pypi.python.org/pypi" attempted to redirect to "https://pypi.org/pypi" during upload. Aborting...
```

The command being executed when this occurs is:
```sh
twine upload dist/*
```
