 * Build the Onyx data and IOU split necessary for splitting a bill with 3+ users.

 * 2. Loop over the group chat participant list, building optimistic or updating existing chatReports, iouReports and iouReportActions between the user and each participant.
 * We build both Onyx data and the IOU split that is sent as a request param and is used by Auth to create the chatReports, iouReports and iouReportActions in the database.
