[SPARK-15480][UI][Streaming]show missed InputInfo in streaming UI
## What changes were proposed in this pull request?
It's a bug in Streaming UI. If BatchDuration is changed by window
operation, InputInfo on time with no output ops will not be shown in streaming
UI.
Here is a simple example to reproduce:
```scala
val inputDStream = KafkaUtils.createDirectStream[String, String,
StringDecoder, StringDecoder](ssc, kafkaParam, topic)
val matchedDStream = inputDStream.window(batchInteval*2, batchInteval*2)
matchedDStream.foreachRDD(rdd => {
val count = rdd.count()
println(s"2 count number: ${count}")
})
```
## How was this patch tested?
