count the group by columns instead of select.*

[pxpm]

WHY

BEFORE - What was wrong? What was happening before this PR?

When having GROUP BY clauses we cannot add any other column to the count that's not on the GROUP BY clause, so our method of select something.* don't work as it would select columns that wont belong to the group by clause.

AFTER - What is happening after this PR?

It's working, it selects the "grouped columns" and don't any other columns to the select that are not in group by.
