[14.0] datev_export_xml double entries in xml

[david-fleischmann]

Module

datev_export_xml

Describe the bug

The datev exort is under certain circumstances having double entries for invoice_item_list

To Reproduce

Trigger xml export of an invoice with configuration "tax_excluded" so only net values are shown in invoice lines.
In the XML file you will have the invoice_item_list entries twice:

In my opinion the error is in line 60 not using t-elif, because if in line 51 t-if condition is met it will be resulting in printing again the invoice_item_list from L59

Expected behavior
having invoice_item_list just once per line in the xml export.

Thanks for the notification. I added the commit to the already open PRs #158 #159 and #160 because it's just easier for me than creating more PRs but I can split it into different PRs if you insist.

@fkantelberg fine for me, thank you! I will close the issue then :)
