[PATCH] bounding box check for hanging entities (#2664) 

This patch intends to fix an issue with LeashHitchs where an exception
was thrown due EntityHanging#calculateBoundingBox not being able to
accept EnumDirections UP and DOWN.

This issue was introduced in a fix for SPIGOT-4674
(d65a2576e40e58c8e446b330febe6799d13a604f)
