Describe the bug

Angular 8+ depends on zone.js@^0.9.1 but nativescript-angular wants zone.js@^0.8.4.

To Reproduce

On a nativescript-angular 8.0.1 project -> Run: npm ls

npm WARN nativescript-angular@8.0.1 requires a peer of zone.js@^0.8.4 but none is installed. You must install peer dependencies yourself.

Expected behavior
No warning about peer dependency.
