resolve() breaks webpack cache parameter

[kennu]

Webpack supports configuring a cache object. But resolve() creates a clone of the cache object, making it impossible to access the cached data afterwards.

My workaround for this is to restore the cache object to the original one. It would be nice if webpack-configurator handled this automatically in resolve():

const resolvedConfig = webpackConfig.resolve()
resolvedConfig.cache = webpackConfig._config.cache
