Conditional Updates using POST not PUT

[brianpos]

Oops.

This is what you're working with

      "request": {
        "method": "POST",
        "url": "SearchParameter?url=http://hl7.org.au/fhir/core/SearchParameter/au-core-practitionerrole-practitioner"
      }

It really should be this

      "request": {
        "method": "PUT",
        "url": "SearchParameter?url=http://hl7.org.au/fhir/core/SearchParameter/au-core-practitionerrole-practitioner"
      }
