Sample reproducing a bug related to UserDefaults in test target

This sample application (and test target) reproduces an issue with UserDefaults where:

• removing objects doesn't have effect
• removing persistentDomain doesn't have effect

The outcome of this investigation are the following rules:

1. If you use the UserDefaults(suiteName:) make sure that

   • the suiteName is in the reverse domain format
   • you have the Host Applicaation set

2. If you do unit tests without Host Application

   • you have to mock UserDefaults
