Given the following chaining:

Promise.resolve(3)
  .map { _ in throw FooError.💥 }
  .map { _ in "foo" }
  .catch { _ in return "goo" }
  .map { $0 }

Logs using print the follwing outputs:

🔗 | PromiseLite<Int> resolves ✅ in 0.00 sec
🔗 | PromiseLite<()> rejects ❌ in 0.00 sec with error: 💥
🔗 | PromiseLite<String> rejects ❌ in 0.00 sec with error: 💥
🔗 | PromiseLite<String> resolves ✅ in 0.00 sec
🔗 | PromiseLite<String> resolves ✅ in 0.00 sec
