contact_info not handled properly when creating registry org

[cberger8]

The handlers for the contact_info field when posting to the create org endpoint with registry enabled expect dot-separated property names (e.g. contact_info.poc), which will not be triggered given a JSON body with the format:

{
  ...,
  contact_info: {
    poc: ...,
    ...
  }
}

This means that the contact_info data will not be reflected properly on the created registry org object.
