Update Test #1

This test verifies your handling of adding 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 send a Webmention to a new URL that appears in the post.

1. Write a post that links to this page, and send Webmentions for your post.
   Verify you see your post as "pending" on this page.
2. Update your post to include a link to https://webmention.rocks/update/1/part/2, and send a Webmention to the new URL.
3. Send a Webmention to the original URL as well. (The order of these is not significant.)
4. You should see your post listed here in the green "Successful Tests" section when complete.
