Subject: [PATCH 1/2] Update fetch-later spec according to WPT expectations

There were two missing parts:
1. The body can either be null or empty (it was missing the
empty case)
2. Quota computation shouldn't include aborted or already
completed requests. WPT uses `AbortController` to ensure
quota is freed up. This also makes sense, since they are
no longer relevant. Therefore, only consider pending
deferred fetches when computing quota.
