[PATCH BlueZ v3] core/device: Fix breakage of Bluetooth pairing

[PATCH BlueZ v3] core/device: Fix breakage of Bluetooth pairing

[Luiz Augusto von Dentz]

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.

v2: Convert the old entries to Services deleting the entries in the process
v3: Save the contents on file
