`/v2/skins`: Missing `dye_slot` overrides

[darthmaim]

Current Behavior

Some (old) skins are missing overrides, here is an example:

(note that all color_id are 1 because of #71)

Data	Ingame
https://api.guildwars2.com/v2/skins/810 ```json { "default": [ { "color_id": 1, "material": "leather" }, { "color_id": 1, "material": "leather" }, { "color_id": 1, "material": "metal" }, null ], "overrides": {} } ```	**Male Norn:**  **Female Sylvari:** 

There are more skins with this issue, for example https://api.guildwars2.com/v2/skins/891

Expected Behavior

The skins should return the correct overrides, like this skin for example: https://api.guildwars2.com/v2/skins/117

Steps To Reproduce

Compare the dye_slots returned by https://api.guildwars2.com/v2/skins/810 with the dye slots rendered ingame. Observe that Human, Norn, and Sylvari female characters only have 2 dye slots ingame, others have 3. The API is missing these overrides
