lua用getcomponent访问时objectpool会有残留的对象引用，导致内存泄露

[WuAlan]

复现代码： lua： self={} self.ShoppingMallPage = self.ShoppingMallPageGameObject:GetComponent("ShoppingMallPageComponent") self.ShoppingMallPage = nil self.ShoppingMallPageGameObject = nil self=nil collectgarbage()

objectpool.cs里还会残留ShoppingMallPageComponent的Type引用
