Review comment:
`UI_ENABLED` is being checked twice, and `.get` is called anyway, defeating
the purpose of Option.
This would behave similar but checks UI_ENABLED only once and leverages
Option properly.
```
sparkSession.sharedState.streamingQueryStatusListener.foreach { listener =>
addListener(listener)
}
```
