AttributeError: 'AzureWorkloadJobTaskDetails' object has no attribute 'start_time'

### Describe the bug

I can list the backup jobs for a recovery services vault by running

`az backup job list --resource-group --vault-name `

However, when running the command to get the details of a single backup job (with the command below), I encounter an error.

### Related command

`az backup job show --resource-group --vault-name --name `

### Errors

The command failed with an unexpected error. Here is the traceback:
'AzureWorkloadJobTaskDetails' object has no attribute 'start_time'
