Fix NPE on null loc for EntityTeleportEvent

Browse Source 
EntityTeleportEvent#setTo is marked as nullable and so is the
getTo method. This fixes the handling of a null "to" location
by treating it the same as the event being cancelled. This is
already existing behavior for the EntityPortalEvent (which
extends EntityTeleportEvent).
