> When resuming from a suspended stream task, today it first transit to
> restoring and then to running. The main motivation is to simplify the state
> transition FSM of stream tasks. We should only call `initializeTopology` when
> transiting from restoring to running, but the tech debt cleanup missed one
> gap that beforehand we transit to running directly and hence also call
> `initializeTopology` at the first transition.
