Contained Observations with more than one note will crash the publisher

[JohnMoehrke]

I had reported this in chat.
https://chat.fhir.org/#narrow/stream/179252-IG-creation/topic/IG.20publisher.201.2E6.2E11.20crash

When an Observation is contained (e.g. DiagnosticReport containing the Observation)
And when the Observation has more than one .note (e.g. note.text)
Then the IG publisher will crash

Note multiple notes does not crash the publisher when they are not contained.

can be reproduced with testMed IG
https://github.com/JohnMoehrke/testMed

The following instance is found in that github, with the second .note commented out to allow the build to succeed.

Instance: ex-labTest-3
InstanceOf: Observation
Usage: #inline

• status = #final
• category[+] = http://terminology.hl7.org/CodeSystem/observation-category#laboratory
• code.text = "Parasitology Remark(s)"
