Pipeline gets stuck due to review-app jobs in deadlock state

review-cleanup was deadlocked, and then rspec:coverage cannot run because it's waiting for all the jobs from previous stages to finish (we may fix this by using needs to replace dependencies), and finally pages which publishes this page is waiting for rspec:coverage to finish because it needs to publish coverage report.
