bluez5: Fix invalid arguments to PairDevice

The third (device class) argument to PairDevice was removed in 0.30.1,
but this call to it was still passing a third parameter, resulting in
an error from dbus-python whenever Pair() was called. This caused a
unit test regression in gnome-bluetooth.

Fixes: 63264e1 "bluez5: Clean up static default properties, re-drop PairDevice class_ parameter"
Fixes #193
