[FIX] gamification: do not group on agregated field for sum

The read_group behaviour has changed and read_group no longer sum on the field you are grouping.
Instead agregate on the field we want to sum and use no groupby.
For future version, grouping on a user such as what is done in batch mode is a better way to process.
