Tag fallback bypasses the bot's DM restrictions #650

When a user issues a command that does not exist, we fall back to trying to match it as a tag name. This means that a message containing !f-strings, which is not a command in itself, will result in the bot sending the contents of the f-strings tag. This is a great feature, but it currently does not respect the DM-restriction we've put in place: Members should only be able to issue commands in public channels, not a DM conversation with the bot.

The current code responsible for the tag fallback only checks if the user is not issuing the pseudo-command in checkpoint. The global checks that prevent commands from being issued in DMs are defined in the security cog.
