The image style upgrade path does not take into account the new image style name/label change that was backported to Drupal 7.23 from #606598: Human readable image-style names. The ImageUpgradePathTest does not use a filled database otherwise this would have been caught by automated tests.
A manual test can be done to reproduce this. Clone Drupal and checkout 7.23 or greater. Install with the standard install. Prepare site for upgrade, checkout 8.x, and run the install. There will be no image styles after upgrade when there were before the upgrade (see screenshots).

mradcliffeHere's a start to changing ImageUpgradePathTest.php, but I am not sure if the thumbnail image style needs to be added as a custom style or not.
Not sending it to the bot.
