gdbus: Remove connection from pending_property functions

The reply to a DBus.Properties.Set() method call should go through the
same D-Bus connection. Thus remove the DBusConnection parameter from the
following functions:

    - g_dbus_pending_property_success()
    - g_dbus_pending_property_error_valist()
    - g_dbus_pending_property_error()
