Add some tests

- the rest of the to-do items are at https://github.com/pypa/pipenv/projects/2
- We just need to review the items in the 'needs tests' column to ensure
  that they either have tests, or don't need to have tests
- If they need tests, and they don't yet have tests, we need to write
  them and make sure they pass
- Then we can release. No more features/bugfixes, this is now how it's
  going out.
