Disable css modules for unit tests

[znck]

Event after setting

cssModules: {
            modules: false,
            localIdentName: '[local]'
          }

class names like foo are transformed to foo_0. There should be a way to disable as unit tests heavily depend on selectors.

Seems useful to me!

I find a simple way to keep the same class name by removing the index suffix for the first <style> tag (of course with @znck 's cssModules config). But if there are more than one <style> tag, the index suffix would be appended from the 2nd one.
