Checking out a PR results in fatal: could not read Username for ...

• Extension version: 0.1.4
• VSCode Version: 1.27.1
• OS: MacOS 10.13.6

Steps to Reproduce:

Using an enterprise github instance, I’ve put the following setting:

    "github.hosts": [
      {
        "host": "https://git.some.internal.corp.com",
        "token": "..."
      }
    ]

I’m able to then get all the PRs on the repo, see diffs, view comments, but when I right click the PR and do “Checkout Pull Request” I get the following:

fatal: could not read Username for 'https://git....com': Device not configured

I’ve figured out reproduction steps:

For a given PR, if I already have a remote for that user e.g.

user1	[e-mail]:user1/repo.git

then it will work.

But if I do not, then a remote will be created which uses https instead of ssh:

user1	https://git.blah.corp.com/user1/repo

This fails as we use only ssh.

Hope this helps.
