The Scoping-element should be added as soom as we want to include
RequesterID, IDPList or ProxyCount in the message. We must therefore
add it even if IDPList isn't specified.

Thanks to Lucas van Lierop for finding this bug!

Scoping allows a sp to give a proxy/bridge idp a list of (backend)idps.
The list can be given as parameters to InitSSO or/and in metadata for
the sp-hosted or/and the sp-remote.

If a message contains a namespace prefix on the root node that conflicts
with the prefix used by simpleSAMLphp, XPath will use the original prefix.

This can be a problem if we receive a message with a namespace prefix
of 'saml' instead of 'samlp'.
