Select active recording if nothing else is selected

[emilk]

What

If nothing is selected (or user presses escape), the active recording gets selected.

In a future PR I will improve the contents of the selection panel when a recording is selected, e.g. show the blueprints in the recording etc, but for that I need to do some refactors first.

I'm not quite happy with the place where you put this in. It's subtle but it creates inconsistent behavior when the selection panel is not shown: When you hide the selection panel pressing escape now has different semantics than when it is shown.
I think this should be handled in a more central place that is always executed.

I also thought this would create strange empty-entries in the selection history still, but that's not the case it seems, so all good on that front!

I moved it to just before showing the selection panel.
