Title: Use class_exists() guard for Featured_Content.

This is a work-around to the problem exhibited by wp-cli/wp-cli#917, where the Twenty Fourteen theme manages to define the `Featured_Content` class first (as plugins are activated *after* the theme is loaded rather than before like core does).

This should ideally still be fixed in WP-CLI, but this workaround would still be helpful in the mean time.
