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

[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.
