Keep a total of enabled hook callbacks in kTotals. This value is used to track whether node::PromiseHook (src/async-wrap.cc) should be enabled or disabled. Don't enable node::PromiseHook, using enablePromiseHook(), until a hook has been added. Then, using disablePromiseHook(), disable node::PromiseHook when all hooks have been disabled. Need to use a native test in order to check the internal field of the Promise and check for a PromiseWrap.
