Fix bug where destroying a namespace would not always destroy projects There is a race condition in DestroyGroupService now that projects are deleted asynchronously: 1. User attempts to delete group 2. DestroyGroupService iterates through all projects and schedules a Sidekiq job to delete each Project 3. DestroyGroupService destroys the Group, leaving all its projects without a namespace 4. Projects::DestroyService runs later but the can?(current_user, :remove_project) is `false` because the user no longer has permission to destroy projects with no namespace. 5. This leaves the project in pending_delete state with no namespace/group. Projects without a namespace or group also adds another problem: it's not possible to destroy the container registry tags, since container_registry_path_with_namespace is the wrong value. The fix is to destroy the group asynchronously and to run execute directly on Projects::DestroyService.
