* Slightly improve ClearDomainMediaService error handling

* Lower DomainClearMediaWorker to lowest-priority queue

* Do not catch ActiveRecord::RecordNotFound in domain block workers

* Fix DomainBlockWorker spec labels

* Add some specs

* Change domain blocks to immediately mark accounts as suspended

complete, but it immediately prevents interaction with the blocked domain,
while up to now, it would only be guaranteed when the process ends.
