NPC "bar" doesn't show up

When an NPC is spawned, they spawn like normal except without the bar floating above their head. During this state, a LUA error is constantly happening in console.

```
[NPC-Information] lua/npcinfo/core/cl_info.lua:32: attempt to index upvalue 'NPCColorBar' (a nil value)
  1. fn - lua/npcinfo/core/cl_info.lua:32
   2. unknown - addons/ulib/lua/ulib/shared/hook.lua:179
```
