Force-clear service worker and caches on SpoolBuddy kiosk load

Browse Source 
Just unregistering the SW wasn't enough — the old SW still controlled
  the page for that load. Now detects if any SW exists, nukes all SWs
  and caches, then reloads once to get a clean fetch from the server.
  Subsequent loads skip this since no SW is registered.
