Robin Gareus 8f5df7ed28 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

```

#4  0x00007fffe2b541ab in ArdourSurface::Console1::set_current_stripable(std::shared_ptr<ARDOUR::Stripable>)
...
```

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