Post Thumbnails: Prevent post thumbnail previews from spilling into other images.

Browse Source 
After [38118], when previewing a page with a secondary loop, all post
thumbnails would be filtered to display the post thumbnail for the
page being previewed. This ensures `_wp_preview_post_thumbnail_filter()`
is only applied if the `$post_id` of the post meta being filtered is
equal to the post or page being previewed.

Props swisspidy, joemcgill.
