   * 2) add a payment of $50 -
   *  This payment transaction IS linked to the line items so $350 of the $300 in line items is allocated
   *  but $200 is paid
   *
   * 3) update that payment to be $100
   *  This results in a negative and a positive payment ($50 & $100) - the negative payment results in
   *  financial_items but the positive payment does not.
   *
   * The final result is we have
   * - 1 partly paid contribution of $300
   * -  payment financial_trxns totalling $250
   * - 1 Accounts receivable financial_trxn totalling $300
   * - 2 financial items totalling $300 linked to the Accounts receivable financial_trxn
   * - 6 entries in the civicrm_entity_financial_trxn linked to line items - totalling $450.
   * - 5 entries in the civicrm_entity_financial_trxn linked to contributions - totalling $550.
