Switch noParse to getter/setter to allow webpack v3 function argument

[eliperelman]

According to the Webpack release notes of v3, noParse supports being defined as a function. Because of this, we can no longer assume that noParse always contains a collection of RegExps, and instead this now has to become a shorthand getter/setter:

config.module.noParse(/something\.js/)

config.module.noParse([
  /a\.js/,
  /b\.js/,
  /c\.js/
])

config.module.noParse(content => /jquery|lodash/.test(content))
