Vehicle Dismount Event Improvements

Browse Source 
player.getVehicle() was returning null during the event. Paper had added lots of code to
cause the player to remount the entity on cancel.

I've simplified the diff and made player.getVehicle() work during the event by setting the
vehicle back during the event, and only set it to null if the event is not cancelled.
