You also have to add defer GinkgoRecover()
The c/storage library is subject to TOCTOUs as the central container and image storage may be shared by many instances of many tools. As shown in containers#6510, it's fairly easy to have multiple instances of Podman running in parallel and yield image-lookup errors when removing them. The underlying issue is the TOCTOU of removal being split into multiple stages of first reading the local images and then removing them. Some images may already have been removed in between the two stages. To make image removal more robust, handle errors at stage two when a given image is not present (anymore) in the storage.
