An error while fetching an image manifest would return a nil
error (hence indicating success) with a unit value image.Info{}
struct.
That is bad news for the caller in Warmer.warm(), which will map an
image tag to that empty image.Info{}, polluting the cache entry for
the image+tag and image in memcached.
When we subsequently use this info to determine the latest suitable
tag, we encounter zero CreatedAt timestamps, which, prior to the
changes in #1247, #1249 and #1250 would cause the wrong images to be
released.
Fixes #1127.
