`tns test init --framework qunit` fails on windows

首先使用 tns create TestApp 运行报告中的 Windows 复现步骤，然后运行 tns test init --framework qunit；检查 CLI 如何解析和安装 QUnit 与 karma-qunit 依赖项。变通方案和 peer dependency 的详细信息表明，重点在于依赖项设置。完成的标准是：无需手动安装 qunit@2，初始化即可成功退出，并且后续测试命令能够正常运行。

Environment
Provide version numbers for the following components (information can be retrieved by running tns info in your project folder or by inspecting the package.json of the project):

• CLI: latest
• Cross-platform modules: latest
• Android Runtime: latest
• iOS Runtime: latest
• Plugin(s): No

Describe the bug
tns test init --framework qunit fails on windows

To Reproduce

tns create TestApp
cd TestApp
tns test init --framework qunit

=> Fails with non zero exit code.

Expected behavior
tns test init to work properly.

Additional context
Looks to be caused by the fact that there is no qunit@2.0.0 version on npm and in karma-qunit package.json we have:

"peerDependencies": {
    "qunit": "^2.0.0"
  },

Workaround
Execute npm i qunit@2 --save-dev before tns test init.
Note that tns test init will still fail, but after that tns test will be fine.
