Clean up duplicate PlayerInitialSpawnEvent
Confused on this one, as commit history says Spigots version is older
than our version, so i'm not sure how we ended up duplicating this when
the 2 events are 100% identical.

Subclass spigots event and rely on the inheritance system, and clean up
the duplicate event fires.

Fix Spigots setPosition to use setPositionRaw to avoid chunk load prematurely.

Subject: [PATCH] Don't move existing players to world spawn
This can cause a nasty server lag the spawn chunks are not kept loaded
or they aren't finished loading yet, or if the world spawn radius is
larger than the keep loaded range.
By skipping this, we avoid potential for a large spike on server start.
