Command `?!help` fails when used via DMs

[StrangeRanger]

Describe the bug If I use the ?!help command in BulletBot's DMs, he will not print out the help text as it otherwise would on a server. On top of this, if I use the ?!status command, it will show that there was an error.

To Reproduce Steps to reproduce the behavior:

1. DM BulletBot ?!help
2. See that it fails
3. Use ?!status
4. See the new error that occurred from the use of the help command

Expected behavior BulletBot should send the help list to you via DM's
