  Fix memory leak when ping-failed contacts unregister.

As for the contacts with failed ping we keep the ping_cell into hash (in order to count the failures), we need a second timer list to be sure that the ping_cellis actually removed from hash as some point. Without this second list, as the ping_cell exists only in hash, if the contact is unregistered, it will never be removed.
