docs(lifecycle-hooks): post-RC5 Dart resync

- TS prose: removed mention of `routerOnActivate` which no longer
exists in the new router.
- TS improvements to the sample code have also been propagated to the
Dart sample.

Contributes to angular#2077.
E2E tests pass now.

+    The router, for instance, also has it's own [router lifecycle
+    hooks](router.html#router-lifecycle-hooks) that allow us to tap into
+    specific moments in route navigation.
+    A parallel can be drawn between `ngOnInit` and `routerOnActivate`.  Both are
+    prefixed so as to avoid collision, and both run right when a component is
+    'booting' up.
