Compile the showcase's views with the showcase off

php artisan view:cache compiles every view in the package's namespace,
the showcase's pages included, but the showcase:: component prefix was
only registered while the showcase was enabled. In production, where it
is off, view:cache failed with "Unable to locate a class or view for
component [showcase::example]" and an application caching its views on
start would not boot. The prefix is now always registered; the routes
still are not.
