test: fix test-performance-measure 
Refs: #42949

Looking at the documentation for setTimeout
(https://nodejs.org/api/timers.html#settimeoutcallback-delay-args)
there is no guarantee that setTimeout won't complete early.

From the failure of #42949 this
is likely what happened.

I have updated the assert.ok test to allow some variation in
the test.
