Fix teleporting onto a chunk line

Obscure detail in that if you teleport right on a chunk line, it
adds +1 to your collision check and will check the unloaded neighbor.

but the call to load the chunk then returned null if it was pending unload, such
as the load we did in Player List

However we want gen=true for players here anyways, so use getType
