Linked packages in `package-lock.json` do not parse

[joshbode]

Thank you for this tool - it is very useful to me :)

Linked local packages in package-lock.json cause an error due to missing version field:

$ git diff

Note: Could not parse /var/folders/8b/xjb2221d1c307gt0k8z_8tjr0000gn/T/git-blob-DRaJ5G/package-lock.json: missing field `version` at line 9604 column 5
Note: Could not parse package-lock.json: missing field `version` at line 9639 column 5

The links are created via the workspaces option in package.json:

{
  ...
  "workspaces": [
    "extensions/*"
  ],
  ...
}

The entries in the lock-file look like this:

    "node_modules/some-local-package": {
      "resolved": "extensions/some-local-package",
      "link": true
    },

I don't believe that version is expected here, since all the information is carried on the package.json in the referenced directory (which does have a version).
