[Svelte] Remove the $updated key

This is probably good to go. Bash it up.

I think Chris should review this one as he was able to reproduce the flickering.
But this looks good and completely explains why there was weirdness.

Sure, that makes sense. For the record, I was able to reproduce the flickering myself while working on 📌 Add a test of multiple project browsers on a page Active . If you check out that branch, enable project_browser_test_mock, then visit /project-browser/project_browser_test_mock?instances=2 and start selecting and deselecting modules for install, you'll see the flickering as well.

Yes, this seems to fix it - I could not reproduce any flickering with this patch.

Automatically closed - issue fixed for 2 weeks with no activity.
