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] Fix issues with entity loss due to unloaded chunks
Vanilla has risk of losing entities by causing them to be
removed from all chunks if they try to move into an unloaded chunk.
This pretty much means high chance this entity will be lost in this scenario.
There is another case that adding an entity to the world can fail if
the chunk isn't loaded.
Lots of the server is designed around addEntity never expecting to fail for these reasons,
nor is it really logical.
This change ensures the chunks are always loaded when entities are
added to the world, or a valid entity moves between chunks.
