[JENKINS-49497] Proxy not set when doing lightweight checkout

I've setup a pipeline project that pulls pipeline script from SCM, and by default "Lightweight checkout"  is checked. This causes an error saying that:

hudson.plugins.git.GitException: Command "git fetch --tags --progress origin +refs/heads/master:refs/remotes/origin/master --prune" returned status code 128:

stdout:

stderr: fatal: unable to access 'https://github.com/owner/repo.git/': Failed connect to github.com:443; Connection refused

When deselecting the Lightweight checkout, the cloning works just fine.

I suspect that the proxy configuration is not passed on to the git client instance that does the lightweight checkout.
