MT#56286 render all subscriber profiles with prof_pref = 1

* on the subscriber profile preferences page, only preferences
  that had enabled attributes plus had prof_pref = 1 were shown.
  that caused confusions as subscriber profile attributes are
  rendered from exposed_to_customer = 1 and do not use the
  prof_pref flag, whereas the rendered preferences do not
  use the expose_to_customer flag and use prof_pref = 1 instead.
  now to avoid the confusions, all voip_preferences that are not
  internal and have prof_pref = 1, shown in on the preferences page
  (and accessible via API). if the list needs to be reduced, then
  it must be properly  done by removing the prof_pref flag for
  them.
