Breaks on install
<!--
Thanks for wanting to report an issue you've found in Crocodile. Please fill in
the template below by replacing the html comments with an appropriate answer.
If unsure about something, just do as best as you're able.

crocodile version: output of `VERSION` file in the root of your project
node version: output of `node -v`
platform: output of `uname -a` (we do not support Windows, sorry)

It will be much easier for us to fix the issue if a test case that reproduces
the problem is provided. Ideally this test case should not have any external
dependencies. We understand that it is not always possible to reduce your code
to a small test case, but we would appreciate to have as
much data as possible.  If your code snippet is long, please link us to a Gist.

Thank you!

Node version: 8.1.2
crocodile version 1.0.4
Macbook Pro x86-64 kernel version 15.6.0

I'm using nvm, brew, mongo 3.4, redis 3.0.4

I can't even get this to work at all.  This is the error I'm getting.

```
An error occured while cloning the repository from GitHub, please try again or file an issue with the below output:

Error: Command failed: git describe --tags `git rev-list --tags --max-count=1`
...
```

I saw that others were having issues as well in issue #220, but doesn't seem to be fixed.  What is crocodile-cli doing?  Should I just clone the project and rename the directory or is it doing more than that?
