Fix console1 crashes when no surface is present 
e.g. selecting a track causes a ControlNotFoundException
if the ctrl surface is enabled, but no hardware is connected.

terminate called after throwing an instance of 'ArdourSurface::ControlNotFoundExceptio

```

...
```

This does at least fix the crash. Ideally the surface would
only be enabled if there is hardware present.
