Handle Hubzilla `Like`s better

[snarfed]

We don't currently translate Hubzilla Like activities to mf2 HTML very well. They have both object and inReplyTo, which arguably they shouldn't, but probably isn't technically wrong. We convert them to a combined reply and like as mf2, which webmention receivers like the WordPress plugin (cc @dshanske) interpret as a reply over a like. (Which is probably right!)

For AS2 Likes, we should prioritize the like and remove the reply when converting to AS1 and/or mf2.

Example: https://authorship.studio/activity/143b8b1d-0bf8-46ab-b0bf-065e689120cd . Pruned AS2:

One of our cats purrs so loudly that it’s a running joke in our family. It makes her fur vibrate. We have to turn the TV volume up when she sits with us. Once, she was in another room, and I heard her purr through the wall. No joke.
