Don't close the BT selection Widget if the local BT adapter is invalid

Browse source 
Don't close the Bluetooth selection widget if the default local
Bluetooth adapter is invalid. Maybe there is a problem with the default
Bluetooth device and the user has another one (a BT dongle) which can be used.

If the selected device is invalid then update the UI information,
disable the available buttons and announce the user about the problem.
Also move the device changed logging message before we call the
update information method. In this way the logging message with
the problem will not be overwritten.
