Fix onOneServer, withoutOverlapping console scheduling options

Flarum doesn't fully use Laravel's cache system, but rather
creates and binds a single cache store.
See \Flarum\Foundation\InstalledSite::registerCache
Since certain config options (e.g. withoutOverlapping, onOneServer)
need the cache, we must override the cache factory we give to the scheduling
mutexes so it returns our single custom cache.
