Some fixes

• Before this update an exception is thrown when you set register_user to false into the package configuration and calling php artisan route:list. This is now fixed.
• This version change the way assets are loaded. Before this update you have to merge webpack.mix.js with the one in the root folder. Now this is not an obligation. You can do it only if you need to add plugins to assets for the back-office.
