Changing prefix into a single character making the bot unusable

[awang-karisma]

Bug Report

Hello, i recently added the bot to my server and trying to change the prefix.
I changed the prefix to dollar sign "$", and then the bot isn't picking any command i typed.
I confirmed it by typing "!say-rollcall" and it is indeed the bot already changed the prefix to "$", but the bot just don't reply to any command i issue, like "$ help" etc

Steps to Reproduce

• Change the prefix to "$"
  !sau config set prefix $
• Check if bot is using the new prefix
  !sau-rollcall
Silence Among Us: @User, I'm listening for $ Try using $ help for more information.
• Try any command with the new prefix, bot won't response
  $ help

Expected Behavior

Bot listens to the new prefix

Ah, I know the problem. That's a special character in regular expressions and I'm not escaping it properly. I'll get that fixed.
