use parse_object_or_die instead of die("bad object")

Some call-sites do: o = parse_object(sha1); if (!o) die("bad object %s", some_name); We can now handle that as a one-liner, and get more consistent output. In the third case of this patch, it looks like we are losing information, as the existing message also outputs the sha1 hex; however, parse_object will already have written a more specific complaint about the sha1, so there is no point in repeating it here.
