message: refactor(service-worker): avoid unnecessarily creating Promises in `Driver#deleteAllCaches()`
  This commit refactors `Driver#deleteAllCaches()` to use `Array#map()`
  instead of `Array#reduce()` for running async operations in parallel.
  This allows avoiding having to recursively wrap Promises with
  `Promise.all()`.
