Fix memory leak by Citizen NPCs (#1693)

* fix: ignore uuid v2 for BukkitPermissionAttachmentManager

Fixes a memory leak that attaches and caches PermissionAttachments to NPCs. Citiziens uses version 2 UUIDs, which are not used for regular player uuids. Those v2 uuids are now excluded.

* fix: create Permission when required

* fix: use citizens documented way to check for NPCs
