There were some problems I introduced with the last PR for this. It passed the test, but failed in practice. This adds tests for those failure cases, adds a "--help" and fixes the test so that it doesn't try and actually download MinGit as part of the Windows test. I added package:platform as a dependency, so I did a force upgrade on the packages. Also, re-enabling 'create package' in the cache warming code, now that #14448 is fixed.
