Fix bug in remote thumbnail search (#8438)
#7124 changed the behaviour of remote thumbnails so that the thumbnailing method was included in the filename of the thumbnail. To support existing files, it included a fallback so that we would check the old filename if the new filename didn't exist. Unfortunately, it didn't apply this logic to storage providers, so any thumbnails stored on such a storage provider was broken.
