When clearing the list, use "history_list", just in case

"history_current" happens to be null (that might not be possible, but
this is still perhaps a bit clearer).

Clear "history_current" after clearing the list, as the current entry no
longer exists, so that "packet_history_add()" doesn't use the now-bogus
value.
