Transaction bundles with conditional create do not apply if-none-exist filters

[JeremiahSanders]

Describe the bug
When processing a FHIR transaction Bundle which contains POST Patient entries with ifNoneExist conditions, search filters contained within ifNoneExist are not applied, which results in failed requests.

When this occurs, ResourceManipulationOperation.GetSearchInformation() specifically indicates that the parameter was unused.

To Reproduce

The following code is the simplest example I could construct. It uses an HL7-provided Bundle and targets the Spark R4 reference implementation.

Steps to reproduce the behavior:

const string xdsBundleUrl = "http://www.hl7.org/fhir/xds-example.json";
var hl7HttpClient = new HttpClient();
var hl7DocumentReferenceBundleJson = await (await hl7HttpClient.GetAsync(xdsBundleUrl)).Content.ReadAsStringAsync();
var hl7DocumentReferenceBundle = new FhirJsonParser().Parse(hl7DocumentReferenceBundleJson) as Bundle;

var fhirClient = new Hl7.Fhir.Rest.FhirClient("https://spark.incendi.no/fhir/");

var transactionResponse = await fhirClient.TransactionAsync(hl7DocumentReferenceBundle);

The example failure is caused by the following entry.request:

{
  "method": "POST",
  "url": "Patient",
  "ifNoneExist": "Patient?identifier=http://acme.org/xds/patients!89765a87b"
}

Result:

The following result was received from https://spark.incendi.no/fhir/ when tested on 2022/11/09. The error occurred at the line executing FhirClient.TransactionAsync.

FhirOperationException

Operation was unsuccessful because of a client error (PreconditionFailed). OperationOutcome: Overall result: FAILURE (1 errors and 0 warnings)
[ERROR] (no details)(further diagnostics: Multiple matches found when trying to resolve conditional create. Client's criteria were not selective enough.
Search parameters not used:Patient?identifier
Search uri used: Patient?
Number of matches found: 292).

Expected behavior
A successful, Bundle response is expected.
