Some commands without arguments throws error

[MinusGix]

If you were to type just /whisper into the chat you would get an error back from the server of: Hook failure, 'in', 'chat': TypeError: Cannot read property 'replace' of undefined This also affects /nick but only the version currently running on the server (the one on github doesn't have a /nick version, only a command version which you'd have to manually send which works fine)

This is due to https://github.com/hack-chat/main/blob/master/server/src/commands/core/whisper.js#L88 not checking if that part of the input actually exists (due to it being undefined if you don't put any spaces).
Easy fix, will make PR to fix it in a short time.

Fixed with 02cec78

I'll get the hooks for the other commands on git this weekend
