While deploying !924 we found out that this script was not working in these cases:

 * when buildout section id contains `-repository` there's a convention that this is stripped and does not appear in test result reference ( implemented [here](https://lab.nexedi.com/nexedi/erp5/blob/31804f683fd36322fb38aeb9654bee70cebe4fdb/erp5/util/testnode/NodeTestSuite.py#L95) )
 * when buildout section id contains `-` this script crash
 * when there's no buildout section id and there's no fix for that, because buildout section id is a required property. If we encounter this failure, we fix the data by putting a buildout section id on test suite repository.
