failing on Jenkins, there is a race between the bindings deletion (part of which can happen
asynchronously) and the shutdown of the virtualhost's task executor.
> In the unlucky case, the asynchronous task is submitted after the task executor has shutdown.
> This could manifest when stopping a VH (either by way of a Management operation, Broker
shutdown, or HA mastership change)
