Fix ExponentiallyDecayingReservoir constant rescaling (#1654) 
This fixes a bug in `ExponentiallyDecayingReservoir` in which the hour prior to the system precise clock (`System.nanotime()`) rolling from `Long.MAX_VALUE` to `Long.MIN_VALUE` caused every interaction with the reservoir to rescale.

It's easy to forget that the tick value is allowed to overflow.

In heavily loaded systems, this results in substantial performance degradation due to write lock acquisition for each update.
