Removes the ATNA logging and old records controller

ATNA logging was never needed for certification. It appears to be
largely unused. This commit removes it. The RecordsController should
no longer be used. Instead the PatientsController in the API should
be used.
Cleaning up the PatientsController

load method appears to be unused. create depended on a class that no
longer exists. create was updated and is now tested.
