    tests/bluez: Follow PairDevice() API change
    
    Upstream python-dbusmock changed its API for `PairDevice()` to include a
    class parameter. For Python code, this API break was solved by providing
    a default value for the argument. Since we rely on the D-Bus interface
    however and D-Bus doesn't have a concept of default arguments, this just
    broke with an error:
    
    > Error setting up mock BlueZ device:
    > GDBus.Error:org.freedesktop.DBus.Error.InvalidArgs: Invalid arguments:
    > More items found in D-Bus signature than in Python arguments
    
    Add the same default argument in our Vala interface to work around the
    problem.
