[xmlsec] xmlsec1 signing wrong when a child has Signature node

[Marcus Pereira]

At a file like the one below xmlsec1 is signing the wrong Signature 
template when I command to sign the Parent node.

# xmlsec1 sign --privkey-pem rsakey.pem --node-id "Child1" xml1_tmpl.xml
OK! it is signing the URI="#Chil1" Signature node.

# xmlsec1 sign --privkey-pem rsakey.pem --node-id "Parent1" xml1_tmpl.xml
NOT OK! it is still signing the URI="#Child1" node not the URI="#Parent1".
