AlterBodySubscriber error when response HTML does not contain ___storybook_wrapper

I am a bit puzzled by this. This code should only execute when sending a response from the storybook.render_story controller. Which in this case is guaranteed to pass those if statements, right?

In any case, I am all in for defensive coding. So I will merge this one.

What we do is clearly atypical and an edge-case.
(Basically we trigger a response event on a fake request in order to trigger response event subscribres on HTML that is rendered separately from the main response, kind of like what big_pipe does.)

I normally would have fixed this on our side, but it seemed like a good occasion to make the storybook code more robust; I am glad we agree on this, thanks!
