Title: Add Jetpack Open Graph tag support for Guest Authors

Jetpack's Open Graph tags break down on Guest Author pages, because Jetpack has no knowledge of CAP and incorrectly attempts to pull user meta from a user with the id of the Guest Author post.

Using the `jetpack_open_graph_tags` filter, we can correct the tags for Guest Authors.
