Debugger detaches during live sync after encountering an runtime error on iOS #201

HI,

Since 4.2.1 and now 4.2.2 of NativeScript and tns-ios: 4.2.0 I have started noticing that the VS Code extension debugger is detaching itself if it encounters an runtime error (tested with error in TypeScript). This same scenario does not hit the same issue if I use Chrome Dev tools to debug (tns debug iOS). Also tested this with the current internal version of the extension.

Here are the steps to reproduce:

  1. In your code make a null reference error: I tested it with simply collating a method on something that is undefined
  2. Hit that part of the code (I did it in the coated of RadListView's itemSwipeProgressChanged event using this sample)
  3. An error is thrown but its should not crash the app
  4. Fix the issue in the TypeScript and save the file
  5. Live sync triggers and prepares the project but detaches the debug session before refreshing the app in the simulator

Here is the callback from the official 0.8.0 version of the extension:

Got the same problem on null object reference.
