tdf#130428 remove unnecessary usage of SfxItemState::UNKNOWN

In this case SfxItemState::UNKNOWN was used as boolean
state to decide to keep extracted value or replace. First
method even throws an exception when SfxItemState::UNKNOWN
should happen.
I tried to be very careful in changing these methods, so
another look/check from reviewers will be welcome. I think
that code was unnecessarily complicated, too, butz hope to
not have touched semantics (behaviour) at all
