Hey ! Thanks for this great library !!

We're getting 'NoneType' object has no attribute 'name_qualifier' when using the saml logout view when the account is a local account (not logged in through saml but through regular django login).

Issue #72 was exactly describing this and was marked as fixed, and has a comment with someone experiencing this after closing, so it looks like a regression.

From the code, it seems like the case where the user has no associated saml session is thought of (it logs a warning), but then not handled (it still runs code to logout from that session).

See: https://github.com/IdentityPython/djangosaml2/blob/1be79465fbf3cc9e2d1685af4639a54ba4d22568/djangosaml2/views.py#L707-L715C43

Affected version: 1.9.2 (django 5.0.4)

Cheers
