Subject: Remove unused NodeSigner implementations in tests
X-Git-Tag: v0.0.114-beta~50^2~4
X-Git-Url: http://git.bitcoin.ninja/?a=commitdiff_plain;h=aee9952ea3d519611ff151599421cd3421d418d0;p=rust-lightning

Remove unused NodeSigner implementations in tests

These implementations have every method panic, so assuming that the test
suite passes, these implementations are never used.
