* 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.
