Handle preference stores corruption by clearing them (#5086)

* Handle preference stores corruption by clearing them:
    - Use the centralised `PreferenceDataStoreFactory` instead of `preferences by`.
    - Add `DefaultPreferencesCorruptionHandlerFactory.replaceWithEmpty` to its `create(name)` method so all preference stores are cleared if they're corrupted.

* Add detekt rule to make sure we use `PreferenceDataStoreFactory` instead of `by preferencesDataStore`

* Remove `@SingleIn` annotations as the annotated class no longer have to be singletons
