[BUG] 4.2.0 breaks builds

[CelsoSantos]

Hello,

The latest version seems to break the builds, at least with Ionic App Scripts v1.2.2.

Error output:

+ npm run build

> com.brandbassador@ build /var/lib/jenkins/workspace/STG-IonicApp
> node --max-old-space-size=2048 ./node_modules/.bin/ionic-app-scripts build

I think Renderer2 was introduced in Angular 4.x, and IIRC ionic-angular@2.x uses Angular 2.x

I'll replace Renderer with Renderer and publish a new release soon.
