 Currently, with a custom post type that no longer exists, a Media object
 that is attached to a post in that custom post type throws a warning.

 To Repeat Warning:
 1. Create a custom post type via functions.php or a plugin.
 2. Create a new post
 3. Upload an image to that custom post type as a featured image
 4. Comment custom post type code in functions.php or deactivate plugin.
 5. Go to Media Library (domain.com/wp-admin/upload.php)
 You will see the warning in the '''Uploaded to''' column.
