Modified the point in ApiDataServiceImpl which calls createOrModify functions to deal gracefully with return of null: don't try to persist
Modified initial history update to no longer delete the existing facets.  This isn't needed since it's use createOrModify.  Added try/catch within createOrModify which skips photos with malformed dates instead of crashing the update.  Added TODO hooks for in the future notifying about the malformed ones.
Added rethrow of UnexpectedHttpResponseCodeException so that the connector will be properly marked as failed.
