Description
Original Downstream Change Summary
Fixed the bug when all aggregations with stage $indexStats incremented Top counters "readLock" and "commands" twice instead of only once.
Description of Linked Ticket
This addition to jstests/core/top.js seems to cause it to fail:

Specifically, that last assertion fails since "commands" is incremented by 2 instead of 1.
