Cannot connect to device socket when you open second tab in Chrome

Try to debug ios on device. If you open URL on second tab you will see that it is empty and exception will throw.

Which platform(s) does your issue occur on?

iOS

Please provide the following version numbers that your issue occurs with:

• CLI: 4.1.0
• Runtime(s): 4.1.0

Please tell us how to recreate the issue in as much detail as possible.

1. tns create app
2. tna debig ios
3. copy the URL and paste it in 2 tabs in chrome
   the second tab is empty and there is error:

    at Errors.fail (/usr/local/lib/node_modules/nativescript/lib/common/errors.js:125:28)
    at Errors.failWithoutHelp (/usr/local/lib/node_modules/nativescript/lib/common/errors.js:135:21)
    at SocketProxyFactory.<anonymous> (/usr/local/lib/node_modules/nativescript/lib/device-sockets/ios/socket-proxy-factory.js:91:38)
    at Generator.throw (<anonymous>)
    at rejected (/usr/local/lib/node_modules/nativescript/lib/device-sockets/ios/socket-proxy-factory.js:5:65)
    at <anonymous>

使用 tns debug ios 复现该问题，并在两个 Chrome 标签页中打开生成的 URL。从 lib/common/errors.js 和 lib/device-sockets/ios/socket-proxy-factory.js 开始，尤其关注报告中的 socket 错误路径。完成的标准是第二个标签页不再为空，并且不再抛出 device-socket 连接错误。
