Removed unnecessary include of CCArray.h 

In the latest version of cocos2dx-v3 CCArray.h is deprecated, so I could not compile cocos2dx-store-example for iOS (file not found error) and since this class is no longer in use, I just removed the unnecessary inclusion of CCArray.h which is moved to deprecated folder in cocos2dx-v3.
