Python prototype registration and session changes

Python prototype registration and session changes

1. Fix registration in python prototype to work again
2. Fix sessions in python prototype to match current API on devsite
3. Fixed issue where "cyphertext" for sessions was going through double
JSON serialization
4. Created empty session without encryption for testing purposes, this is
different from the dummy session in that it is a complete passthrough

This is an argument to an external function. registrationTicketId is the name of
the argument.
