Check if the .git directory exists before invoking git

AndyShawQt · kkoehne · commit 5fc3be56ea6c · 2016-11-10T12:04:56.000Z
If .git does not exist then this is not from a git build and therefore
there is no reason to invoke git (which might not even exist on the
system anyway). This prevents an error appearing due to trying to invoke
git on Windows when it does not exist.
