LiveSync (too many redeploys for a single code change)

[albertobastos]

Looks like livesync has introduced some issues after 4.0 upgrade. When changes are detected, it seems that the "behind the curtain" work done by both the TypeScript compiler and the TNS Runtime mark as changed additional files also detected by the livesync, so a tiny change in the code ends up launching several deploys one after another.

I tested it with a just-created app using the nativescript-template-ng-tutorial, and adding a single Label to the main screen forced up to three re-deploys. In a bigger app such as the one I'm working on, changing a single comma now gets more than 90 seconds to be effectively deployed at the emulator :(

Scenario:

SO: Windows
Platform: Android
CLI version: 4.0.0
tns-code-modules version: 4.0.0
Runtime version (tns-android): 4.0.1

How to recreate it:

• Create a starter app using the nativescript-template-ng-tutorial template.
• Ensure the modules are updated with "tns update"
• Launch livesync at emulator with "tns run android"
• Save a minor change (for instance, adding a Label or a Button to app.component.ts) and watch the console output.

Console output:

@albertobastos thanks for reporting and logging this issue. I can confirm hat indeed on Windows the live sync is executing the Angular bootstrap 4 times.
Steps to reproduce:

• use this project or create sample Angular project
• run the application and made some minor code change
