Can't re-add recently removed emotes

[JunkiEDM]

If someone tries to re-add an emote (or one with the same name) that was recently removed, it will say "emote code already added"

Same issue as Nerixyz/rewards#156, which means its probably a 7TV API issue, not sure if it's the endpoint for retrieving enabled emotes or if it's the endpoint for adding emotes.
If it's the former you might be able to get around it with a cache or by querying their Event API in some way.

Yes it's a cache issue. Chatsen has a similar issue.

This is too much of an edge case for me. It's not worth implementing the whole event api just because someone wants to add an emote with the same code.

Instead we should support aliasing emotes in gempbot
