route:cache causes "Channels" to dissapear from routes

[mwargan]

When calling route:cache in Laravel apps using packages defined with:

 $package
            ->name('my-chat')
            ->hasRoutes('channels', 'api');

The "API" route correctly get cached, but the "channels" get discared, lilely because they are callback based routes, which Laravel cannot cache.

Whats the best approach here configure the package for "channels" routes?
