line[].tradeSettlement.allowances is missing ChargeIndicator

[kilbiller]

To Reproduce

1. Create a EN16931 invoice with discounts on line items in the form of allowances
2. Check the xml output

Current vs. Expected behavior

A Charge indicator set to false should be present at the top but nothing is set, i also tried adding chargeIndicator: false to the object but it does nothing.

Here is what is generated :

      <ram:AssociatedDocumentLineDocument>
        <ram:LineID>2</ram:LineID>
      </ram:AssociatedDocumentLineDocument>
