package-lock-only tests

README.md

made a folder called install-package-lock-only containing only a package.json with these contents:

{
  "name": "install-package-lock-only",
  "version": "1.0.0",
  "dependencies": {
    "mkdirp": "^0.3.4"
  }
}

Then I ran:

scripts/maketest install-package-lock-only  > test/tap/install-package-lock-only.js

And that produced the first revision of the attached file. Then I edited it to do pass in the command line option and have comments about the assertions we'll want.
