Fix an issue where viewing an autosave created on a post without any previous revisions would throw a PHP notice. Also fixes the revision screen which was broken in these cases and showed a console error. Props iseulde. Fixes #31249. git-svn-id: https://develop.svn.wordpress.org/trunk@50128 602fd350-edb4-49c9-b593-d223f7449a82
