  fix: improper relative cursor movement (#1462)

Fix a wrong relative cursor movement when a new calculated index is
negative (beyond the first row). According to the java-doc, in this
case the position leaves before the first row. Current implementation
of the 'relative' method delegates the movement to the 'absolute' method
which treats a negative index with respect to the end of the result set.
