Delete orphaned reference author names

[jonkerz]

Only old cases. There should be no new cases after 68739cd

These: ReferenceAuthorName.where.not(reference_id: Reference.select(:id)).count # ~250

• Run script

jonkerz = User.find 60
Activity.execute_script_activity jonkerz, "Delete orphaned reference author names, see %github706"

# For PaperTrail
antcat_bot = User.find 62
PaperTrail.whodunnit = antcat_bot.id

# For the activity feed
User.current = antcat_bot

class ReferenceAuthorNameObserver
  def before_destroy _
    # Suppress `reference_author_name.reference.invalidate_caches`
  end
end

ReferenceAuthorName.where.not(reference_id: Reference.select(:id)).each(&:destroy)
