IMPALA-5679: Fix Parquet count(*) with group by string

In a recent patch (IMPALA-5036) a bug was introduced where a count(*)
query with a group by a string partition column returned incorrect
results. Data was being written into the tuple at an incorrect offset.

Testing:
- Added an end to end test where we are selecting from a table
  partitioned by string.
