Authority Migration (to become Lakeshore Bootstrapping?)

Migrating Authority References

First, run:

`` bash RAILS_ENV=production bundle exec rake lakeshore:load_lists

This command will fail with `ActiveFedora::IllegalOperation: Attempting to recreate existing ldp_source`, but it will have also created the necessary resources to proceed with:

``` bash
RAILS_ENV=production bundle exec rake authorities:migrate

This will alter the model type (:hasModel) of the offending authorities that caused the previous error. Now, you may re-run the original command to complete the authority creation process:

RAILS_ENV=production bundle exec rake lakeshore:load_lists
