[PATCH] bluetooth: fix missing 'connected' notifications (rh #1255284)

[Dan Williams <dcbw redhat com>]

Because Bluez5 dropped DUN support, NM must do that manually which
includes emulating the "connected" property for Bluetooth devices when
DUN is used.  It does this by setting priv->connected = TRUE in
nm_bluez_device_connect_finish().

But for PAN, when NM does process the 'connected' property change
notification, priv->connected is already TRUE and
_take_variant_property_connected() does nothing.  Hence the
corresponding GObject property notification is not emitted,
nm-device-bt.c::check_connect_continue() will never return success, and
the activation times out.

To fix this, ensure that GObject notifications are emitted when the
device is connected, even if emulated internally.
