Bump pipenv version

[allyjweir]

We are depending on some of the bug fixes released between the last version and 11.10.4 (VCS package related issues). Having updated locally for our dev envrionments, thought it was worthwhile to bump the version in the buildpack in use too.

Tests are failing on Travis:

testPipenvLock
ASSERT:Captured exit code - expected:<0> but was:<1>
-----> Installing python-3.6.5
-----> Installing pip
-----> Installing dependencies with Pipenv 11.10.4…
       Your Pipfile.lock (d26635) is out of date. Expected: (00ad98).
       Aborting deploy.

I went into the fixtures for the failing test and tried running pipenv lock to regenerate the Pipenv.lock file. Unfortunately this didn't generate a new lockfile with the required hash. @kennethreitz (or any other maintainer with pipenv experience!), any advice on how to resolve this issue?

Thanks in advance.

that should do the trick!

Figured out my issue. My local install of pipenv wasn't at latest version so was getting different hash when running pipenv lock using my local machine.

Now getting a shellcheck failure on Travis but not locally. Will update as I progress...

@hone this looks good to me. I updated the branch so it would merge cleanly. (I had missed that @allyjweir had fixed the shellcheck violations.) Would you mind giving this a look over as well for compliance?

Looks good to me. @sigmavirus24 feel free to merge on Monday.

What's the process for this becoming in use in Heroku dynos?

@allyjweir This pull request was release with V135 so it is now available to run on your dynos, next time you do a build it should pick up the new version.

P.S I also used to work at Twig, say hi to everyone for me!
