`lightningd --version` prints plugins that failed to register

[daywalker90]

lightningd --version
2026-06-04T13:02:34.895Z UNUSUAL plugin-manager: failed to register plugin /usr/local/bin/../libexec/c-lightning/plugins/bwatch/bwatch
v26.06

I use this in CI to check the version and i expect it to print just one line with the version and no failed plugin registrations.

see this too when using lightningd --version
