Continued:
- removed findContactById() as this was a performance problem and it should be
  done all on WAR side (relying on JCache then)
- removed findContactByEmailAddress() as this was no longer used outside the
  EJB's own method and would be a performance problem, too.
- the application then needs to rely on it's cache or fetch whole list and
  check that list then (but I recommend first as 2nd is "same in green color)
