Fix SCSS rule detection to use correct RegExp test method

Changed from incorrect '.scss'.match(rule.test) to correct
rule.test.test('.scss') in webpack configuration.

The previous code was calling match() on a string with a RegExp
parameter, when it should use the RegExp's test() method to check
if a string matches the pattern.

Fixed in both:
