Fixed issue where default values on xcdatamodel was causing issues. Bug #3794

I tracked down the issue to be related to the fact that the default values in the xcdatamodel were set to 0.

I removed the default value boolean for the following:

DispositionCode
- categoryCode
EventTemplate
- eventRepeatKey
- eventTypeCode
MdesCode
- localCode
Person
- prefixCode
- relationshipCode
- suffixCode
Provider
- practiceNum
Response
- responseGroup
