Pre-reporting checklist

• I have searched existing issues and didn't find any previous reports of this bug.
• This bug still happens in the latest version of Wurst. I've made sure my installation is up to date.
• I have tried removing all other mods and the bug still happens.

Description

Right now, ProfileKeys is created whenever an alt is selected, even if the alt is cracked (https://github.com/Wurst-Imperium/Wurst7/blob/master/src/main/java/net/wurstclient/mixin/MinecraftClientMixin.java#L220). This doesn't cause any issues in game, besides an error message that shows up every time a server is joined.

#1069 fixes this.

Repro steps

1. Switch to a cracked alt via AltManager.
2. Login to any server.
3. See the below error message in logs:
