Non Image Attachments Throw Notices

[christianmagill]

If you have an attachment that is not an image in your media library, then wp_get_attachment_image_src will return false and thus not have an array offset.

'Notice: Trying to access array offset on value of type bool in /Users/christianmagill/Code/Sites/extended/wp-content/plugins/jarvis/src/php/models/post.php on line 21'

You can make use of https://developer.wordpress.org/reference/functions/wp_attachment_is_image/ to qualify the conditional.
