[PATCH BlueZ 2/3] client: Fix not releasing agent if bluetoothd exit without calling Release

[Luiz Augusto von Dentz <luiz.dentz@gmail.com>]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

If AgentManager1 disappear the agent should auto release itself
otherwise next time AgentManager1 appears bluetoothctl wont register
the agent again.
