Plugin remove fails if plugin version is not available in npm

[dtopuzov]

package.json:

{
  "nativescript": {
    "id": "com.telerik.plugindemo.barcodescanner",
    "tns-ios": {
      "version": "1.7.0-2016.2.23.1"
    },
    "tns-android": {
      "version": "1.6.2-2016.2.22.2"
    }
  },
  "dependencies": {
    "nativescript-barcodescanner": "1.2.1",
    "tns-core-modules": "file:../tns-core-modules.tgz"
  },
  "devDependencies": {
    "nativescript-dev-typescript": "^0.3.1",
    "typescript": "^1.8.2"
  }
}

tns plugin remove nativescript-barcodescanner
npm WARN package.json @ No description
npm WARN package.json @ No repository field.
npm WARN package.json @ No README data
npm WARN package.json @ No license field.
version not found: nativescript-barcodescanner@1.2.1

=> and pacakge.json is still the same, plugin not removed.

Tested with CLI in master.

This bug makes building sample apps for verified plugins hard.

Same applies if I have reference to local file and this file does not exist.

"dependencies": {
        "nativescript-imagepicker": "file:../../dist/package",
        "tns-core-modules": "1.5.0"
}

npm WARN package.json ExampleImgPick@0.0.2 No license field.
