service worker: Bump update time even when the script was identical

This regressed in https://chromium.googlesource.com/chromium/src/+/57ebec5b7cce00100000763371c56bc4991b56dd

Also make the unit test more thorough and realistic:
* It was using StopWorker() when the script was identical, but after the change above
production doesn't take that path
* don't use force_bypass_cache_for_scripts since in production that's only used
by DevTools
