TAJO-1793: result row count unmatched for UNION ALL
When executing an union all query, there isn't TableDesc in ```Query```.
As a result, the result stats of last stage will set output row number and
volume.
To resolve this issue, I summarized each result stats of all stages in
union all query. But I found that the bytes number of stage changes
occasionally. So, I just compare row number except bytes number in unit tests.
