Fix broken seeder 11.6

What does this MR do?

It seems there are two problems

• https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/22308 => Calling ClusterProjectConfigureWorker.perform_async(@project.id) in Project::CreateService

• https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/23217 => Calling UpdateHeadPipelineForMergeRequestWorker.perform_async (via Ci::CreatePipelineService) in MergeRequest::CreateService Those are failing because it's not wrapped by skipping_transaction_check

What are the relevant issue numbers?
