Update payment data
-remove calculatedTotal from registrants
- save total due in registrants once registration is complete
- if total due is not present in database, calculate total due, otherwise use total due in database
Error in ConferenceResource
- There seems to have been an error in the ConferenceResource. The registrationEntity.setCompleted is set to false; however, this was never saved in DB. When performDeepUpdate() is called, it is passed a completed registration, and the registration that was saved in the DB is also completed. This meant that the CompletedTimeStamp is never added because it is never seen as not completed.
Update how admin payment override is handled.
- Since registrants will now save total due, this should be able to be updated by admin.

Start work on using contact info tables (cherry picked from commit 60de412)
