Reduce quote usage to bypass bug in git-lfs

[guillep2k]

Fixes #7888

This is related to git-lfs/git-lfs#3131 (comment)

@zeripath would you please test this PR on your setup? It works for me.

For context, in my environment I've got:

$ git-lfs version
git-lfs/2.4.2 (GitHub; linux amd64; go 1.9.4)

And the git-lfs version where they've fixed this problem (git-lfs/git-lfs#3199) is v2.6.0.

I wasn't able to run integration tests; ssh would keep asking to add localhost. Even if I answered yes to every prompt, git-lfs tests failed anyway.
