 * 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.
 * The IOU split has the following shape:
 *  [
 *      {email: 'currentUser', amount: 100},
 *      {email: 'user2', amount: 100, iouReportID: '100', chatReportID: '110', transactionID: '120', reportActionID: '130'},

 *  ]
 * @param amount - always in the smallest unit of the currency
 * @param existingSplitChatReportID - the report ID where the split expense happens, could be a group chat or a workspace chat
