Slowly attaching to debugger on real iOS device with bundle

[DimitarTachev]

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: 5.1.0
• Cross-platform modules: 5.0.0
• Android Runtime: 5.0.0
• iOS Runtime: 5.0.0

To Reproduce

1. tns create testApp --ng && cd testApp
2. tns debug ios --bundle (or launch the VSCode task with --bundle)
3. try to hit a breakpoint
4. you will have to wait for ~1-3 minutes based on the device performance

Expected behavior
The breakpoint should be available just after the app is started.

Additional context
After tracing the debug protocol, it seems that the delay is caused by the "{"method":"Debugger.scriptParsed","params":{"scriptId":"1","url":"file:///app/vendor.js"..." message. The file huge and the runtime needs much time in order to parse its source maps.
