Added test case 560:

This test was added after the HTTPS-using-multi-interface with OpenSSL
regression of 7.19.1 to hopefully prevent this embarassing mistake from
appearing again... Unfortunately the bug wasn't triggered by this test, which
presumably is because the connect to a local server is too fast/different
compared to the real/distant servers we saw the bug happen with.
