🍕 Fix pre-publish site controller reference

[jjpaulino]

This function is not being executed in our clay instance because it is not being picked up and assigned to the site's controller. It's a function to add metadata to a page's meta.

Nice catch.

i know this is just like.. the pattern set by whoever came before, but wouldn't this be written more simply as

    _.assign(site, {
      providers,
      // things to remember from controller
      ..._.pick(controller, 'resolvePublishing', 'resolvePublishUrl', 'modifyPublishedData', 'assignToMetaOnPublish')
    });

or like.. w/o lodash...

    Object.assign(site, {
      providers,
      // I don't know why it's important that we not just assign everything from the controller
      resolvePublishing: controller.resolvePublishing,
      resolvePublishUrl: controller.resolvePublishUrl,
      modifyPublishedData: controller.modifyPublishedData,
      assignToMetaOnPublish: controller.assignToMetaOnPublish
    });
