Review Comment:
It can't, i guess... because this is an infinite stream. if we use something
like:
```scala
override def persistenceIds(): Source[String, NotUsed] =
currentPersistenceIds()
.throttle(1, readJournalConfig.refreshInterval)
....
```
It only queries once, and then throttles the set of ids in flight.
