[PATCH BlueZ v2] core/device: Fix breakage of Bluetooth pairing

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

From: Jakub Pawlowski <jpawlowski@chromium.org>

This patch converts old propertis containing list of services available
on remote devices. Without that previously paired devices, i.e.
keyboards, will not work properly.
