Update Test #2

This test verifies your handling of removing a link when updating a post. You will pass this test when you both re-send a Webmention to a previously mentioned URL, as well as re-send a Webmention to a URL that you removed from the post.

1. Write a post that links to https://webmention.rocks/update/2 and https://webmention.rocks/update/2/part/2, and send Webmentions for your post.
2. Verify you see your post as "pending" on this post.
3. Update your post and remove the link to https://webmention.rocks/update/2/part/2, and send Webmentions for your post again, to both URLs.
4. You should see your post listed here in the green "Successful Tests" when complete.
