The libpod manifest-create endpoint takes an "images" query parameter that
fills the new list at creation time, but 15-manifest.at never tested it.
Add cases that create a list with images= on both the v4
(/manifests/{name}, 201) and v3 (/manifests/create, 200) endpoints and
check the image ends up in the list.
Also drop the stale "required: true" from the images query parameter in the
swagger docs - the handler treats it as optional, and the existing create
tests (which omit it) already show that.
