LGFM. I cannot believe, it completely did not work after #850

[DeMoorJasper]

Some assets already have their own resolver instance. Could you clean this up a bit and remove those, and reference them to this.resolver instead of creating their own. (As your Pr adds one to the asset instance, they no longer need to create one themselves, they can utilise the one in asset)~

I think the ones with their own resolver instance are SASS, LESS and Stylus

EDIT: On second thought this could probably break on css imports that don't define an extension, what do you think?

[marcosbozzani]

Maybe I can create a logic that checks whether the assets already has a resolver or else use the default one.
I'll analyse the code and try to come up with a solution.

I've had a little chat with @fathyb about the possible side-effects of my remark and it's probably a better idea to keep this as is.
So feel free to ignore my previous requested changes.

[absentees]

@marcosbozzani does this work for you now? I'm still getting the same errors on your example repo, and on my own.
