[FLINK-1813] Avoid illegalstate exception when trying to broadcast on
finished operators

> Barrier broadcast sometimes causes illegal state exception in source

> Issue Type: Bug
> Components: Streaming
> Reporter: Gyula Fora
> Assignee: Gyula Fora

> The StreamCheckPointingITCase sometimes fails on an illegal state exception
> thrown when trying to broadcast barrier from the sources. I think this is
> caused by sending a barrier when the source is not running any more.
> The exception:
> Exception in thread "Thread-341" java.lang.RuntimeException:
> java.lang.IllegalStateException: Partition already finished.
