issue(errors): error handling stops working

[dylanvdmerwe]

Short description of the problem:

Errors are not being handled correctly in latest app-scripts. Break the .ts of a starter app. Run ionic serve and you'll get the nice error page. Make a small change to the html or another file and save (while keeping the broken ts) and you'll see ionic serve now runs?

What behavior are you expecting?

Errors should always be caught and show the error page when not in prod mode.

Which @ionic/app-scripts version are you using? 3.0.1
