    Fix GPG test
    
    At least GnuPG, when run with both --fingerprint and --with-colons will output
    the fingerprint of the public key and the subkey. The command below will thus
    output two fingerprints and the delete command will fail because it cannot
    find the second fingerprint (which is a subkey and not a public key). It seems
    that a safe approach is to consider only the first fingerprint line.
