UserDefaults Bug

Automated Test to demonstrate bug in iOS UserDefaults

Step to reproduce:

1. Open Project in Xcode 9.2
2. Select iPhone X Simulator
3. Run tests by pressing Command-U or Select Product->Test in the menu
4. If test pass run again
5. Notice test failed. To restart delete the app on Simulator

Explanation

This test simply saves and read two different values in UserDefaults. It should be repeatable and passing all the time.
