Remove leftover line from spigots tick limiters
Looking over the code, this appears to be one "high risk but hopefully
unlikely that plugins are causing this to break", this line is however
redundant leftovers from spigots tick limiter patch, which should be
doing nothing as-is.

Subject: [PATCH] limit the range at which we'll consider an attackable target
This patch aims to ensure that MCP World#getNearestAttackablePlayer
will not trigger chunk loads due to PathfinderGoalNearestAttackableTarget
performing a ray trace operation by pre-checking the maximum limit;
Given that the implementation shows that the limit should only ever
decrease when set, allowing us to skip further checks earlier on
when looking for an attackable entity
