Fix placement of chunk tracking - Fixes #1199

Spigot had code that returned early in chunk add/remove methods.

This was causing our code added to set current chunks and counts to
be skipped over if the entity was default not persistent but made persistent.

This was the source of many issues

Fixes #1208
