Conor O'Donnell d45bc14cce Keep strong reference to OnSharedPreferenceChangeListener (#131) ...

Summary:
A strong reference to the listener should be kept when calling `registerOnSharedPreferenceChangeListener`, otherwise the listener can get garbage-collected and stop working.

Mentioned in the Android SDK docs [here](https://developer.android.com/reference/android/content/SharedPreferences.html#registerOnSharedPreferenceChangeListener(android.content.SharedPreferences.OnSharedPreferenceChangeListener)):

> Caution: The preference manager does not currently store a strong reference to the listener. You must store a strong reference to the listener, or it will be susceptible to garbage collection. We recommend you keep a reference to the listener in the instance data of an object that will exist as long as you need the listener.
