test: update anthropic http image test for url-forwarding behavior

The async completion test asserted the old behavior where http:// image
URLs were downloaded and inlined as base64. Since http:// URLs are now
forwarded as url sources like https://, the test asserts nothing is
downloaded and both images arrive as url sources.
