Fixes combination of cached routes and hide default locale in URL (#651)

* Fixed loading of translated cached routes in console context

Used to only work for requests, since it depended on the request segment to read the locale. Now, LaravelLocalization's current locale is used.

* Fixed route cache and list command for Laravel 5.8

* Fixed hide default locale in URL flag not working when routes are cached

This fix ensures that no locale string is returned from `::setLocale()`, even when routes are cached, for the default locale, when this config flag is enabled.
