TargetToTarget with ReflectedWorkItemId

[djbyrd]

I think there is an order of operation issue with TargetToTarget field mapping, specifically with the ReflectedWorkItemId. When using the field mapping as documented in the Test Plan migration guide, it seems the TargetToTarget is happening before the target is updated with the ReflectedWorkItemId. So, my target ends up with a blank IntegrationBuild field. If I re-run the migration then it gets updated the second time around.
