[SPARK-17851][SQL][MINOR][TESTS] Update invalid test sql in
`ColumnPruningSuite`
## What changes were proposed in this pull request?
The `originalQuery` in `ColumnPruningSuite.test("Column pruning on Window
with useless aggregate functions")` will fail at `SimpleAnalyzer.checkAnalyze`,
because it has expression neither presents in `group by` clause nor an
aggregate function.
## How was this patch tested?
Manually.
Before, `SimpleAnalyzer.checkAnalyze` on this plan will fail:
```
SimpleAnalyzer.checkAnalysis(originalQuery.analyze)
org.apache.spark.sql.AnalysisException: expression '`b`' is neither present
in the group by, nor is it an aggregate function. Add to group by or wrap in
first() (or first_value) if you don't care which value you get.;
```
After the update, this would pass checkAnalyze.
