telecom: Ensure that we always update bluetooth in dsda case

If you do not send the bluetooth headset service phone state
information then headset calls (SCO) will not work.

The reason that the state must be passed along for the calls
to work is that (in 6.0) there is now a check against the
current call state before allow SCO connections from the
headset (in packages/apps/Bluetooth):

    Do not accept SCO without any active listener.

However, in the DSDA case we do not send any phone state updates
if there is no BluetoothDsdaService then we neither send updates
to it nor to the HeadsetService.

Fix the couple of cases where it does not handle this correctly
which fixes bluetooth (SCO) calls on DSDA devices.
