Animation without Transition: TypeError: Cannot read property 'callbacks' of undefined

[Harald-1]

Unfortunately, I found another bug. Steps to reproduce:

• Take 11.a "The animate directive" from the tutorial (https://svelte.dev/tutorial/animate)
• Remove the transitions and just leave the animation
• Tick or remove a todo from the list
• See the exception on the console:

Uncaught (in promise) TypeError: Cannot read property 'callbacks' of undefined
    at on_outro (eval at handle_message (about:srcdoc:13), <anonymous>:288:16)
    at outro_and_destroy_block (eval at handle_message (about:srcdoc:13), <anonymous>:296:9)

Here is the REPL: https://svelte.dev/repl/405d24c6f8414e528c67596fc8f382f1

I'll provide a fix (pull request) shortly. 😉

I am sorry for the superfluous commits, I forgot to branch before committing. 🙈

I'm getting a cannot read property '_callbacks' of undefined using sveltenative textLayout.

Likely an issue with sveltenative but just commenting here because it's a similar problem.

EDIT: seems to happen every second liveupdate, probably sveltenative problem
