This rev. is related to rev. 89093a2
If several account analytic lines where defined for a same date
within a same sheet, the report totals were multiplied by
the number of occurences of lines of the same day.
Before the above rev., only `Diff`, `Total`, `Timesheet`, were wrong
After, other totals were wrong as well.
The point of the above rev. was to gain a real performance improvment
when there was a lot of timesheets / analytic lines entered
in database. This rev. keeps this performance improvment.
