Subject: Add workaround for test-bundler failure

https://github.com/ruby/actions/runs/500526558?check_suite_focus=true#step:16:127
```
Failures:

  1) Bundler.setup when Bundler is bundled doesn't blow up
     Failure/Error: expect(err).to be_empty

       expected `"fatal: not a git repository (or any of the parent directories): .git\nfatal: not a git repository (o...the parent directories): .git\nfatal: not a git repository (or any of the parent directories): .git".empty?` to return true, got false
