Adding routes to group doesn't work #258

Hello,

I've tried to change the default route by grouping it like so:

$routes->group('account', function($routes) {
service('auth')->routes($routes);
});

But it doesn't work as expected, visiting account/login OR account/register, returns a 404 error and when I run php spark routes command, it shows:

account///login
account///register

I understand that from the docs, it is possible to customize the routes, but what if I just want to put all the routes in a group, without having to do that for all individual routes?
