Thanks for submitting the fix @ianda

A couple of things:

• It would be great if you could try to add a unittest that failed because of this bug, and is fixed by this change
• Could you please sign the CLA?

* It would be great if you could try to add a unittest that failed because of this bug, and is fixed by this change

This is not the coolest test but testing that something is not there is often not so cool. The best would be something that parses the file, but that seems to be overpowered to me. Are you ok with the implemented test?

* Could you please sign the CLA?

CI is broken, but seems unrelated to your changes: https://ci.conan.io/blue/organizations/jenkins/ConanTestSuite/detail/PR-9480/4/pipeline

Don't worry about it, we will have a look.
