Automated Error Report: DataIntegrityViolationException: not-null property references a null or transient value: org.openmrs.PatientIdentifier.dateCreated; nested exception is org.hibernate.PropertyValueException: not-null property references

This error can be recreated by these steps:

1. Go into the patient edit short form for a patient with a single OpenMRS Identification Number
2. Add a new OpenMRS Identification Number (e.g., 9-1) and mark it as preferred
3. Remove the original identifier
4. Try to save the changes

I see this exception consistently using the OpenMRS standalone, every time I try it.
