Fi 600 build errors

[arscan]

Occasionally there are build errors on the practitioner role chain tests. One problem seems to be that inferno tests are trying to hit example.com/Practitioner... instead of example.com/fhir/Practitioner... and that could be because we haven't set a url on the testing instance.
