+Subject: [PATCH] Fix NPE on null loc for EntityTeleportEvent
+
+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).
