Seth Brenith aae45ca822 Avoid leaking Promises when detaching debugger 
When the debugger is active and a Promise begins executing,
Isolate::PushPromise adds a global handle for that Promise. If the
debugger is no longer attached when the Promise finishes executing, then
there is no corresponding call to PopPromise which would clean up the
global handle. To avoid leaking memory in that case, we should clean up
the Promise stack when detaching the debugger.
