Description
The problem
Whenever starting LiveSync on a new project if LiveSync is unable to start (for example a TypeScript error is present) then CLI tries to exit, but hangs because it has child processes attached to it.
Steps to reproduce
On a Unix OS:
tns create myApp --tsccd myAppecho asd >> app/app.ts// this will cause the transpile errortns run android// could be ios just as well
At this point CLI fails to start LiveSync, because there is a syntax error in the main TypeScript file and the message Unable to apply changes on device: XXXXXXXXXXXXXX. Error is: TypeScript compiler failed with exit code 1. is displayed, however the process does not finish and the user is forced to break execution with Ctrl-C.
This issue is caused by the various child processes that CLI spawns like the one for communication with iOS devices or analytics.
