[PATCH BlueZ 4/8] gdbus: Fix emitting PropertiesChanged twice

[Luiz Augusto von Dentz <luiz.dentz@gmail.com>]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

This fixes double emission of PropertiesChanged introduced by flushing
changes, the flushing can happen during the pending processing so the
pending_prop flag needs to be updated in the beginning and the list of
properties can be freed before g_dbus_send_message as it is not required
anymore.
