No stack traces on error

[ckeeney]

When a command throws an error, the error message prints to the console but not the full stack trace. This makes development very difficult.

Example:

// ./commands/debug.js

const anotherFunction = () => {
    throw Error("you can't find me.")
}

const aFunction = () => {
    anotherFunction();
}

export default async function debug() {
    aFunction();
}
