error: 'native-ios-app': invalid custom path 'Artsy' for target 'eigen'

Hi,

Steps to reproduce:

1. Installing Danger through homebrew: brew install danger/tap/danger-swift
2. It creates Dangerfile.swift with the following content:

// swift-tools-version:4.2
import PackageDescription

let package = Package(
    name: "Eigen",
    dependencies: [
      .package(url: "https://github.com/danger/swift.git", from: "1.0.0")
    ],
    targets: [
        // This is just an arbitrary Swift file in our app, that has
        // no dependencies outside of Foundation, the dependencies section
        // ensures that the library for Danger gets build also.
        .target(name: "eigen", dependencies: ["Danger"], path: "Artsy", sources: ["Stringify.swift"]),
    ]
)

3. Running swift build swift run danger-swift pr [url_of_pr], and getting the following error:
   error: 'native-ios-app': invalid custom path 'Artsy' for target 'eigen'

Tried to install Eigen globally, but it does not help get rid of this error.

Does your local project have a path named Artsy? The path, and it's sources needs to be changed to fit your project.
