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

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.

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。
