Perry Jiang 96edc2a092 Bug 1557244 - Disallow resurrection of unregistered ServiceWorkerRegistrations r=asuth
- Remove `ServiceWorkerRegistration`s' pending uninstall flag.

- Rename `ServiceWorkerRegistrationListener`'s `RegistrationRemoved` method to
  `RegistrationCleared`; registrations are no longer necessarily consider
  invalid when they are removed from the "scope to registration map", but rather
  when they're both removed from the map and not controlling clients (at which
  point `Clear` is called).

- Maintain the invariant that no `ServiceWorkerRegistrationInfo` in
  `ServiceWorkerManager::RegistrationDataPerPrincipal::mInfos` (i.e. the "scope
  to registration map") is in the unregistered state. Assertions check this in
  `ServiceWorkerManager::AddScopeAndRegistration` and
  `ServiceWorkerRegistrationInfo::SetUnregistered`.

- Fix some incorrect web platform tests.
