[4.0.0.rc.1 / 4.0.0.rc.2] stylesheet_pack_tag is broken

[VR4J]

I've upgraded from 4.0.0-pre.3 to 4.0.0-rc.2 and I noticed my stylesheets weren't included into the rails view.

This misbehaviour seems to be caused by this call in my project:
/app/views/layouts/application.html.haml

= stylesheet_pack_tag 'css/app.css'

It didn't cause any error's as it just seems to not generate the style tag in the html.

When downgrading to 4.0.0-pre.3 it worked again.

Have you added extract_css option? #1625

@gauravtiwari Yep, that fixed it thanks!
