Refactor user/<user_id>/code into two endpoints.

- Created new endpoint user/<user_id>/sms-code to send the sms verification code to the user.
- Create new endpoirtn user/<user_id>/email-code to send the email verifcation code to the user.
- Marked the old methods, schema, tests with a TODO to be deleted when the admin app is no longer sending messages to /user/<user_id>/code
- Added error handlers for DataError and NoResultFound. Data error catches invalid input errors.
- Added error handler for SqlAlchemyError which catches any other database errors.
- Removed the need for the try catches around the db calls in the user endpoints with the addition of the db error handlers.
- We may want to wrap db excpetions in the dao, if we want the No results found message to be more specific and say no result found for user.
