couldn't open an app if you make a change in debug command with bundle

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: 5.2.4

Describe the bug
When you run debug with bundle and make a change, you will see exception:

Unable to start application org.nativescript.appNG on device f42eb590ec7ad920c8c0545a308e1a1d2551218b. Try starting it manually.
Cannot connect to device socket. The error message is 'The application org.nativescript.appNG does not appear to be running on f42eb590ec7ad920c8c0545a308e1a1d2551218b or is not built with debugging enabled. Try starting the application manually.'.
NativeScript debugger was not able to get inspector socket port on device f42eb590ec7ad920c8c0545a308e1a1d2551218b for application org.nativescript.appNG

To Reproduce

1. tns create app --ng
2. tns debug ios --bundle
3. make a change
4. when app restarts it couldn't open

Expected behavior
to open an app

首先使用 tns create app --ng 和 tns debug ios --bundle 重现问题，然后检查源代码更改后 CLI 的 iOS 调试重启路径。完成标准是应用能够正常重启并打开，且没有调试器套接字错误。
