[FIX] pivot: running total display with multiple measures

[hokolomopo]

Description

The running total computation was wrong in pivot if there was multiple measures: the pivot cells were not filtered by the measure on which the running total was computed, which led to the same cell being counted multiple times.

The display rank ascending/descending had theoretically the same issue, but since pivot cells with the exact same value have the same rank, it didn't end up impacting the final result.
