Call log respects display name order preferences

- Updated ContactInfoHelper to retrieve DISPLAY_NAME_ALTERNATIVE (name
  in last name first order)
- Stored alternative name in ContactInfo object
- Updated CallLogAdapter to choose between first name first and last
  name first when showing contact name
- Added tests for ContactInfoHelper.lookupContactFromUri (changed to
  public method)
- Fixed bug with ContactsPreferences so ChangeListener works
