#156 isPrimary NullpointerException

[RikuNieminen]

Getting primary address for contact doesn't work right
because of spelling mistake. In select sql "IsPrimary"
should be "isPrimary" otherwise when you later ask if
address is primary you get NullpointerException. This
bug doesn't show in user interface, it shows only when
you do some new services that use centraview beans.
