[SPARK-18852][SS] StreamingQuery.lastProgress should be null when recentProgress is empty
## What changes were proposed in this pull request?
Right now `StreamingQuery.lastProgress` throws NoSuchElementException and it's hard to be used in Python since Python user will just see Py4jError.
This PR just makes it return null instead.
## How was this patch tested?
`test("lastProgress should be null when recentProgress is empty")`

Closes #16273 from zsxwing/SPARK-18852.
