Pipeline fails although excessive isa metadata is provided

[andreaschrader]

To add this specific case here as well.

This public ARC constantly fails the validation pipelie as no xml file ist written.
It contains excessive isa metadata and was already closer inspected by @omaus
It was found that the ORICD entries were not causative as I assumed but parsing one cell from the isa.investigation.xlsx file failed which did not cause a problem in the ARCPrototype which only had a different value there.

Maybe @omaus can specify this here as it might be causative for others as well when the validaton pipeline fails.

I hope this is caught by c03db33 for now, if this still occurs when we migrated to v2, we have to investigate this further.
