RFR: 8333270: HandlersOnComplexResetUpdate and HandlersOnComplexUpdate tests fail with "Unexpected reference" if timeoutFactor is less than 1/3 [v2]

[Daniel Fuchs]

> HandlersOnComplexResetUpdate and HandlersOnComplexUpdate tests verify that loggers are GC'ed (or not GC'ed) after a reset or an update. For that they poll a ReferenceQueue in a loop. The number of iteration is adjusted according to the jtreg timeout factor. However, the logic in the test did not expect that the timeout might be less than 1.
> 
> This fix does two things:
> 
> 1. fix the adjustCount logic - so that the number of iteration can only be increased
> 2. use remove(timeout) instead of poll() in order to minimize the waiting time.
