Issue Description:

Test code:

import ArgumentParser
import Foundation

@main
final class Example: ParsableCommand {

    enum MyError: CustomNSError {

        case exampleError

        var errorCode: Int { 23 }
        var errorUserInfo: [String: Any] { [NSLocalizedDescriptionKey: "Hello World"] }
    }

    func run() throws {
        throw MyError.exampleError
    }
}

Expected Output:
"Error: Hello World" with exit status code 23

Actual Output:
"Error: exampleError" with exit status code 0

This worked correctly previously …

Tested Using Swift Argument Parser v0.3.2:
Exit status code: 23
Output: "Error: Hello World"

Tested Using Swift Argument Parser v1.0.2:
Exit status code: 1
Output: "Error: exampleError"

… so this appears to be a regression.

Closing as invalid since this has been covered in the Argument Parser repo.
