Title: InstrumentedHandler: Remove duplicate calls to activeRequests.dec()

I've been playing with InstrumentedHandler and noticed that the active-requests counter decreased by one on every request. I believe this is the correct fix: The counter is decremented inside updateResponses(), but the callers for this function also did the same thing.
