Prevent unsanitized queries from creating Cloudflare errors

[No767]

Summary

This actually has been a bug for a long time, but I haven't noticed this. Within the dictionary commands, you can send an invalid query (e.g. for SQL injection), and Cloudflare would block it. This would result in a content type being HTML, and a HTTP 403 status code would be sent from Discord. There were some folks who abused this to try and get Catherine-Chan to crash thinking that error handling was not implemented and an attempt to block the event loop (which never happened as Catherine-Chan uses aiohttp for HTTP requests, not the requests library)
