Bug Report

Tell us about the problem

The on() and addEventListener() methods exist on the NS Page object, so the Page object is never extended and the special First events are never defined.

Which NativeScript version and platform does your issue occur on?

Using "tns-core-modules" version 5.4.1 with Angular and TypeScript.

Any steps to duplicate?

Simply run the app and observe that the First events (i.e. Page.navigatingToFirst) are not defined.
