Modified devise.rb example for SSO

Had to remove code that was building devise omniauth connections dynamically. The timing of when the rails engine builds the routes and the models is not conducive to this approach

fixed typo in devise.rb.example

Added check to devise initializer so that it does not try to access the IdentifierSchemes table before it has been created (happens when running db:migrate)

Fixed the way params are pulled into the identifier scheme intialization

Updated devise initializer to load orcid omniauth provider without params

renamed example files which get loaded by rails and cause configuration problems.
