status untracked returns all files when ruby working directory is not same as git repo root

[asymptotik]

Subject of the issue

I was attempting to use ruby_git in fastlane which runs with the working directory under /fastlane. When attempting the following code, I get all the files:

require 'git'

git = Git.open('../')

p 'Untracked: '
git.status.untracked.each { |s| 
  p "#{s.to_s}" if s[1].untracked
}

If I run that some code in my repo root except with git = Git.open('../') I get the expected results which is just the files that are untracked.

Your environment

git version 2.18.0
ruby 2.6.0p0 (2018-12-25 revision 66547) [x86_64-darwin18]

Steps to reproduce

Tell us how to reproduce this issue.

Expected behaviour

I expected my program to exhibit the same results no matter where it is run provided that Git.open is passed the proper path to the repository root.

Actual behaviour

See above.

I will have to reimplement how Git::Base#status fetches untracked files to actually use git status. I am afraid this will stay one the back burner for a bit longer.
