Includes: * Adjusting test method descriptions and comments per the documentation standards. * Creating image editor class instances directly, instead of calling `wp_get_image_editor()`. * Cleaning up temporary files before performing assertions, where possible. * Using more consistent variable names for image editor class instances. * Reordering some test methods. Follow-up to [1182/tests], [1188/tests], [27794], [30549], [30990], [31040], [39580], [40123], [49230], [49488], [49542], [49751]. See #55652. git-svn-id: https://develop.svn.wordpress.org/trunk@54401 602fd350-edb4-49c9-b593-d223f7449a82
