`ngOnInit` is called multiple times in production mode if an error happens in it

This is because we are setting `ViewState.FirstCheck` not until a view has been fully change detected.

Solution:
```
detectChanges(view: ViewData) {
  view.wasFirstCheck = view.firstCheck;
  view.firstCheck = false;
  // dirty check all directives, use view.wasFirstCheck instead of view.firstCheck.  
}
```
