HeartBeat packet has some invalid information.

[Masahito Muroi]

Heartbeat packet doesn't include correct service's information.

How to reproduce:
1. define following rule.
// ID: 0b3049a6-e1b8-4c09-8610-8664cb90e7e9
// Name: test
server_id(x):-nova:servers(id=x)
2. check logs on engine node and datasource node

Unexpected behavior:
1. subscribed_tables of engine node's packet doesn't show service id that subscribes another service's table. It only shows '0'.

2. subscribed_tables of datasource node's packet doesn't show subscribing service id. It also show '0'.
