DurableTask.Sql - ErrorPropagationMode - UseFailureDetails not populating FailureDetails

Unclear if this is an issue with the SQL provider implementation or the core, but before starting the hub worker, I'm setting:

`_hubWorker.ErrorPropagationMode = ErrorPropagationMode.UseFailureDetails;`

However, across the entire chain of the orchestration execution every instance of `TaskFailedException` has `FailureDetails` set to null, and ultimately the `OrchestrationState` that comes back also has `FailureDetails` set to null.

I'm trying to preserve stack trace information rather than the serialised output just being the exception message.

At every point during the orchestration I can see the `OrchestrationContext` does have `ErrorPropagationMode` set to `UseFailureDetails` (in non-public members).

I'm using the following packages:

- Microsoft.DurableTask.SqlServer - 1.0.1
- Microsoft.Azure.DurableTask.Core 2.11.1 (dependency brought in via .SqlServer)
