flake8 would have caught the regression in #371 and output:
`pipenv/cli.py:257:19: F821 undefined name 'hashed_deps_path'`
Whilst in an ideal world there would be 100% test coverage, linters help
fill in the gaps, plus spot potential unused variable/imports cleanup.
I'm happy to disable more of the style/whitespace pep8 rules if
needed - the priority is having the pyflakes subset run in CI.

Previously doing `pipenv install "django-rest-auth[with_social]==0.8.2` would
lose the extra information and if you edited the Pipfile by hand to
```
[[source]]
url = "https://pypi.python.org/simple"
verify_ssl = true
[packages.django-rest-auth]
version = "==0.8.2"
extras = [ "with_social",]
```
`pipenv update` would break with a malformed pip command.
