[SPARK-18868][FLAKY-TEST] Deflake StreamingQueryListenerSuite: single listener, check trigger...

## What changes were proposed in this pull request?

Use `recentProgress` instead of `lastProgress` and filter out last non-zero value. Also add eventually to the latest assertQuery similar to first `assertQuery`

## How was this patch tested?

Ran test 1000 times
