Previously, when failing to load a signing key, ‘guix authenticate’ would
print a backtrace and exit with a non-zero code. That, in turn, would lead
the guix-daemon child process to crash with:
nix/libutil/serialise.cc:15: virtual nix::BufferedSink::~BufferedSink(): Assertion `!bufPos' failed.
This patch fixes it by reporting the error to the daemon as was intended.
* guix/scripts/authenticate.scm (guix-authenticate): Arrange to call
‘load-key-pair’ from within ‘with-reply’.
* tests/guix-authenticate.sh: Test it.
