    Skip or retain project while deleting the project:

    * Skip Ci::Build#update_project_statistics whenever there's no
      project (i.e. we're deleting the project!)
    * Retain the unscoped_project before deleting the build,
      so that we could use the data to delete the artifacts.
      Note that carrierwave uses `after_commit` for this,
      so we need to retain it in the memory.

    Closes #15005
