Setting git config to use ssh instead of https breaks cloning from public repositories

[Pi-George]

This line in git clone shallow:

git config --global url."ssh://git@github.com".insteadOf "https://github.com" || true

Is causing composer install to fail with:

Also worth noting, checkout is checking out a bitbucket repo, not a github repo.
