In I0a9eb0ad we fixed a NoteDb-specific issue where loading the default search results page caused ChangeNotes to get loaded, despite not causing changes to load from ReviewDb. Support this configuration in tests by adding a method to NotesMigration that is called in AbstractChangeNotes#load(). In production this method always returns false so the cost is negligible.
