Default apps settings disappear when switching to secondary user

When switching to a secondary user, Settings will disable all extra
categories that aren't configured in SETTINGS_FOR_RESTRICTED.
As the result, Default apps settings disappear.
To fix this issue, AdvancedAppsActivity class of Default apps settings
should be added to SETTINGS_FOR_RESTRICTED.
