Adding rake task to migrate state property to Sipity

Fixes #955

The task should probably set the resource.state to nil or Vocab::FedoraResourceStatus.active. Otherwise, CC is going to hide them by default.

We should pull all the IDs from Solr and then ActiveFedora::Base.find each one, so we don't have to hold all those objects in memory.

Simpler/faster would be

ActiveFedora::SolrService.query("has_model_ssim:#{model}", fl: "id").map{|x| x["id"]}.each do |id|

👍 — I also noticed that I had book_works hardcoded, so I replaced that with a hash of workflows to models they contain.
