Fix problem with loading css/scsss

[LokiMidgard]

As long as the localIdentName was set in the parameter the modules parameter was ignored. This resulted in the use of modules even when modules was set to false explicitly

Overview

Fixes #343

The problem was introduced in #243. It fixed a problem with invalid options, but always set the module option for the css-loader.
This prevented the styles to get applied since the name of the style was changed in the css but not in the DOM.

Test Notes

Thanks for doing this! You'll also need to run yarn change to generate a change file.

@ecraig12345 is it possible to crate this file manual?
I'm not very keen on installing a bunch of dependency's on my machine, I will probably never use again, just to add an additional check to one if.

[ecraig12345]

@LokiMidgard Maybe, but it would probably be easier to just clone the repo, yarn, yarn change, then delete it when you're done.
