Change logging to provide more information on LLUDPServer.HandleCompleteMovementIntoRegion() 

Add more information on which endpoint sent the packet when we have to wait and if we end up dropping the packet
Only check if the client is active - other checks are redundant since they can only failed if IsActve = false
