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