Use AR::CounterCache#update_counters directly
Use AR::CounterCache#update_counters directly

Instead of using the ActiveRecord::CounterCache#increment_counter and #decrement_counter,
use the lower-level #update_counters method, because it will eventually enable us to
control the amount of the increment or decrement.  Otherwise, the amount is hard-coded
to 1 or -1.
