Regression report with empty `CrashTestResult`

[tevoinea]

Information

• Onefuzz version: 8.6
• OS: N/A

Provide detailed reproduction steps (if any)

We are getting some regression reports where the CrashTestResult has null CrashReport and null NoReproReport. Technically, according to our model this is possible:

onefuzz/src/ApiService/ApiService/OneFuzzTypes/Model.cs

Lines 533 to 536 in 9c4bc3e

	public record CrashTestResult(
	Report? CrashReport,
	NoReproReport? NoReproReport
	) : ITruncatable<CrashTestResult> {

How is there a RegressionReport with no CrashTestResult?

The symptom that led to this report was a high amount of these log messages:

onefuzz/src/ApiService/ApiService/onefuzzlib/NotificationOperations.cs

Line 191 in 9c4bc3e

_logTracer.LogError("unable to find crash_report or no repro entry for report: {report}", JsonSerializer.Serialize(report));
