=act #15165 should fix out-of-bounds in actor creation

Should fix index out of bounds in actor creation.

* Improved actor creation tests to take into account GC pauses (coordinated omission)
* Also improved failure logging when AIOOB happens in the histogram
* Added a test which shows why the updateWithExpectedInterval method should be preferred too.

May resolve #15165, we'll need to get a failure now to get the min/max bounds and the value it failed at to set the bounds even better (histogram's max tracked value).
