[SPARK-23222][SQL] Make DataFrameRangeSuite not flaky

## What changes were proposed in this pull request?

It is reported that the test `Cancelling stage in a query with Range` in `DataFrameRangeSuite` fails a few times in unrelated PRs. I personally also saw it too in my PR.

This test is not very flaky actually but only fails occasionally. Based on how the test works, I guess that is because `range` finishes before the listener calls `cancelStage`.

I increase the range number from `1000000000L` to `100000000000L` and count the range in one partition. I also reduce the `interval` of checking stage id. Hopefully it can make the test not flaky anymore.

## How was this patch tested?

The modified tests.
