When services, characteristics and descriptors were parsed from DBus
proxies the client code was calling the print code without initializing
the `handle` field, which the print functions use.
This resulted in semi-random or zero handles in all attributes when
using gatt.list-attributes in bluetoothctl, depending on compilation
flags.
This patch fixes the problem by parsing the handle from the DBus proxy
path.
