SPIGOT-5562: Entering a boat triggers VehicleExitEvent 
This patch prevents entities from riding a vehicle they're already riding on.
When trying to enter a boat the client will send up to two packets for each hand
causing the server to think they should enter the boat twice, despite the first
interaction being sufficient.
