Subject: Fix INVALID_REF errors caused by mods (#657)

`INVALID_REF` errors were being caused by trying to get the item image for weapon skins.

If a mod (e.g. moreskins) added new skins, the client equipped one, and then the mod is disabled, the client now has bad persistence.
This is mostly handled fine by the game, except for weapon skins. This PR prevents the crash, and resets the bad persistence to default.
