After npm install, tsconfig.json is being forced to 4 spaces changing other settings like adding es6 to lib.

Ideally, there should be a "nativescript": { "lastMigrated": VERSION } flag that can be added to the tsconfig.json so that after a migration is done and then the project is readjusted, it doesn't get run again until a new version/migration is available.
