Properly support multi-user in NotificationSettingsRepository
(And also in every place that injected SecureSettingsRepository / SystemSettingsRepository).
This also:
* adds some methods to UserAwareSecureSettingsRepository (via the base class) and their tests.
* removes the UserAwareSecureSettingsRepository interface/impl/fake split.
* adds a UserAwareSystemSettingsRepository (same base class, but interacting with SystemSettings instead of SecureSettings).
