schema update
[Fixes#71801996] Deletes services when provider is deleted. Hacky controller-based solution.
[Fixes#72717142] Revokes anonymous_traveler role upon user signup.  This was messing with users available to staffing agencies
[Fixes#73571196] Missed a few instances of the partial which needed a local.  Adds in the 'for_db' local, which is responsible for persisting a snapshot of planned itineraries
Hopefully this will get schema.rb to stop reverting to include rates table
