eir interprets commands as ban annotations if btset was used in a channel

[ghost]

Steps to reproduce:

1. Set a ban in a channel.
2. Do !btset BAN_ID comment in the ops channel of the channel.
3. Try to use some other command in a query with eir, such as btinfo.

Expected behavior: eir replies to your command as usual.

Actual behavior: eir will interpret your command as a comment for the ban.
