bug: Component Editor - Some non-Python components cannot be edited

[Ark-kun]

I think this happens when componentRef only has .spec, but no .text.
This does not happen for new components, but some old components might be brokken.

@Ark-kun do you have component (name from Standard lib) to test with?

[Ark-kun]

I think this cannot be a component form the standard lib. Those components all have texts.
All user components should have texts too. But apparently there was a period of time where they did not (only spec was saved).

There is likely a place in component editing code where we mishandle missing component.Ref.text
