`[object Object]` issue for some summaries

See: https://webmention.herokuapp.com/api/embed?version=cutting-edge&url=http://www.kevinmarks.com/twittereditsyou.html

For some reason the .summary of one of the comments there is an object rather than a string, making the presentation fail:

He's using e-summary, not p-summary so you get the more complex structure. Also it looks like you're using an older version of the microformats parser that doesn't suppress implied name when there is a summary.

Great, thanks 👍 I'll try to fix it soon

Yes, I'm tracking swapping out the parser in #154
