Fix not working --disable-rating switch (3.3dev)

The logic was wrong when calling set_rating_state() in parse_cmd_line() as do_rating was set before to true through set_scanning_defaults().

This PR fixes #2825 by querying ${SKIP_TESTS[@]} instead and then calling set_rating_state() when no --disable-rating was supplied .
