Select a bluetooth enabled model as the default

Using a bluetooth enabled model (e.g the OSTC 2) as the default choice
is very convenient when using only the --family command-line option to
scan for bluetooth devices or establish a connection. That's because
after commit ce2c3c6, the filter will
no longer result in a match for the non-bluetooth enabled models.
