reason for $cql evaluation failure should be returned to the end user

[kmbarton423]

Running with 4.11.0-SNAPSHOT in local docker container.
Attempting inline $cql where the "subject" does not exist:
GET .../$cql?expression=[Patient] p where p.gender = 'male' &subject=Patient/bogus

Received 500 Internal Server Error:
{
"resourceType": "OperationOutcome",
"id": "ac-11-0-2-61e18333-1ed9-4cf1-9fc2-e8da1ada0661",
"issue": [
{
"severity": "fatal",
"code": "exception",
"details": {
"text": "FHIROperationException: Evaluation failed"
}
}
]
}

From the log, you can see that the reason for the failure is known (see attached "tracePatientBogus.txt"):
java.lang.RuntimeException: com.ibm.fhir.persistence.exception.FHIRPersistenceResourceNotFoundException: Resource 'Patient/bogus' not found.

Suggest a better explanation to the end user about the failure.
