Do not show an error notification when the WorkerRunDetails modal fails to retrieve a WorkerRun
Refs teklia/requests#798
When the RetrieveWorkerRun
API request fails, we do not need any notification: the WorkerRunDetails modal can already show a more permanent error state.
We could store the backend error message in the component's data
and display it here, instead of showing a notification, which will make the error easier to read.
