Issue Description:

The following Package.swift file will crash the dependency resolver:

// swift-tools-version:5.3

import PackageDescription

let package = Package(
  name: "PubGrubCrash",
  products: [
    .library(name: "PubGrubCrash", targets: ["PubGrubCrash"]),
  ],
  dependencies: [
    .package(url: "https://github.com/RxSwiftCommunity/Action.git", from: "4.2.0"),
    .package(url: "https://github.com/ReactiveX/RxSwift.git", from: "6.0.0-rc.1"),
  ],
  targets: [
    .target(name: "PubGrubCrash", dependencies: ["Action"]),
  ]
)

It results in the following fatal error:

% swift package resolve
