Unwanted error handling in command suggestions.

[Qwerty-133]

Description

The bot sometimes sends you error messages when you type invalid commands.

Steps to Reproduce

Type ...and or .cand or so on in a channel, and you'll be met with an embed by the bot saying "Command can only be used in October." This happens because the command handler tries suggesting the candy command but its checks raise a check failure, and the check failure is passed to the error handler again which is handled by it by posting that october embed.

Expected Behaviour

The bot shouldn't send any message at all.
