Avoid 'forcedSAML' in Choice module
With Choice module, we are forced to check the lmAuth paramater to know which module must be used. This is a problem with SAML, as the lmAuth parameter cannot be added to redirect URI (which is set in metadata).
As a workaround I called authForce of SAML and add on the fly a Choice entry named forcedSAML. But this does not work if we configured a SAML choice which is not SAML;SAML;Null.
I propose for 1.9 to find which Choice entry is SAML if we have an SAML response to manage, and to remove all forcedSAML related code.
In 2.0, I see that @guimard removed all forcedSAML mention. I'm not sure this is working...
