Safety 2.x fails when git is not installed

[andyjones]

Thanks for safety!

I get the following error running safety 2.x:

FileNotFoundError: [Errno 2] No such file or directory: 'git'
Unhandled exception happened: [Errno 2] No such file or directory: 'git'

It looks like Safety 2.x introduces some checks to see if this is in a git repo. This check fails when the git binary is unavailable (eg. running safety against a dockerised application).

Reproduce the issue by running safety when git is not in the path eg.

python -m venv .venv
. .venv/bin/activate
pip install safety
PATH="`pwd`.venv/bin" safety check

Hey @andyjones - thanks for the PR!

We're going to merge this in ASAP and get 2.1.1 released with it included.

Looks like all of our tests run in containers that have git installed, so we didn't pick this up before release - I'll add a few new cases once the release is out to make sure we catch this case going forward.
