GEODE-10130: Check containsKey under synchronization. (#7452)

* containsKey in HashMap can return false even though the key exists in
   the map possibly due to map resizes as other concurrent operations
   occur. Now it will be checked under synchronized lock.

> In geode, cq event for replicated region are cached so that when destroy event comes in, we can just use cached value to determine if a client need the cq event (instead of evaluate the query again for performance). 
> However, there is a synchronization issue in ServerCQResultsCacheReplicateRegionImpl that could cause geode failed to find the cached event.
