Unable to debug when project's app directory is renamed

[rosen-vladimirov]

NativeScript CLI allows you to change the name of the app directory in the project by adding a nsconfig.json with the following content:

{
    "appPath": "src"
}

After that you can safely rename the app dir to src and CLI will build the project and livesync and debug will still work. However, debugging in VSCode is not working as the mapping between files on device and the local paths is not correct.

This breaks debugging of newly created NativeScript Angular projects (tns create myapp --ng), which already have nsconfig.json and have src dir instead of app.

Scenarios that should be tested on both iOS and Android:

• [x] Debug application that does not have nsconfig.json and the app directory is called app
• [x] Debug application that has nsconfig.json, but there's no appPath property in it.
• [x] Debug application that has nsconfig.json with appPath set to different dir, for example "src" and ensure you've renamed "app" dir to "src".
• [x] Debug application that does not have nsconfig.json. Stop the debugging. Add nsconfig.json, add "appPath" property in it, rename the "app" directory. Start the debugging again.
