If the cursor is not yet initialized, MovePrevUnique is identical to
MoveLast(LockingInfo). Otherwise, move the cursor to
the previous non-duplicate key in the database, and store that key
and associated datum in Current. MovePrevUnique will
return false if no non-duplicate key/data pairs exist after the
cursor position in the database.
