templates: render like and bookmark posts correctly

They really use the same framework, so for now a unit test for like
posts is sufficient. Of course, for proper coverage, one can introduce
tests for bookmarks too, especially if one chooses to render them
differently. The logic will be pretty much the same though.

Replies might use the same logic, since those are also
Webmention-oriented posts.

(It looks like another way to classify MF2 documents is slowly forming
in my brain. Maybe I should write about it on my blog.)
