Revert "Flip histograms to true by default, fix unit in isac_fix_test."

This reverts commit 7b201012bc7f7cd95249b8314d0d7ebabe966d8b.

Reason for revert: Seems to work, but need to get low bw tests working first

Original change's description:
> Flip histograms to true by default, fix unit in isac_fix_test.
> 
> Requires downstream changes for all WebRTC perf tests, and
> a corresponding recipe change so isac_fix_test starts using the new
> flow.
