wrong task hub name is used for durable functions 2.x with durable commands

[collinstevens]

Version

4.0.5907

Description

using any durable function command defaults the task-hub-name parameter of those commands to DurableFunctionsHub.

DurableFunctionsHub is the default task hub name in Durable Functions 1.x only.

if ran against a Durable Functions 2.x project, the default TestHubName, is not picked up and resources are created in the storage account named according to DurableFunctionsHub and the requests aren't processed by the function app.

Steps to reproduce

create a .net8 isolated function app from the visual studio template with a durable function selected as the function for the template

broken

run func durable start-new --function-name Function1 observe Function1 never starts and it created the resources in your storage account

workaround 1

run func durable start-new --function-name Function1 --task-hub-name TestHubName observe Function1 running to completion

workaround 2

set extensions:durableTask:hubName to "TestHubName" (which is the default) run func durable start-new --function-name Function1 observe Function1 running to completion
