[SPARK-19774] StreamExecution should call stop() on sources when a stream
fails
## What changes were proposed in this pull request?
We call stop() on a Structured Streaming Source only when the stream is
shutdown when a user calls streamingQuery.stop(). We should actually stop all
sources when the stream fails as well, otherwise we may leak resources, e.g.
connections to Kafka.
## How was this patch tested?
Unit tests in `StreamingQuerySuite`.
