Conflict between Text and UiImage components when a ui node has both

What went wrong

If you add both the image and text components to a UI node you get a mess:

Until archetype invariants can be enforced (#5121), users can't be prevented from adding both components.

It's natural for a user who wants to add a caption to an image to naively add text components to an ImageBundle and sometimes it will work.

What solution would you like?

I think only drawing the text, and emitting a warning explaining why the image isn't shown is probably the best that can be done for now.

A node can't be both text and an image at the same time, but we can't prevent someone from adding both components without #5121
