Subject: Replace `lightning-block-sync` test that depended on `foo.com`
X-Git-Tag: v0.0.118~19^2
X-Git-Url: http://git.bitcoin.ninja/?a=commitdiff_plain;h=refs%2Fheads%2F2023-10-no-test-net;p=rust-lightning

Replace `lightning-block-sync` test that depended on `foo.com`

Our tests should generally not rely on internet access, and should
not rely on the behavior of any given remote server. However, one
of the `endpoint_tests` in `lightning-block-sync::http` relied on
`foo.com` resolving to a single socket address, which both might
change in the future and makes our tests fail without internet.
