Kamat, Trivikram 92ee8b7f50 test: avoid timer race in event loop delay test ...

An expired timer can run before the first complete event loop
iteration, disabling the histogram before it records any samples.

Drive a known number of iterations with setImmediate before checking
the histograms, and share the chain between resolution variants.
