Fix another race in Notification Queue
Summary: Consider a case we found that the queue is empty and unlocked and before our setActive(false) from SCOPE_EXIT gets called (or gets the lock) putMessageImpl got the lock. Now putMessage thinks that we donot want to add another signal but actually we do. Test Plan: Running mcreplay2 without running into this problem on a box.
