MT#56234 get_usr_preference changes

* as_admin param is no longer needed as get_usr_preference()
  fetches actually set preference for a susbcriber and used
  only by the code (not exposed directly to 'subscriber',
  'subscriberadmin' roles
* with the aforedescribed, get_usr_preference() no longer
  filters by expose_to_customer, expose_to_subscriber for
  'subscriber' and 'subscriberadmin' roles
* refactor get_usr_preferences() to be simple and in line
  with the other get_*_preferences() as it's mainly responsible
  for fetching the preference as requested by the internal
  code
