[backend] Fixing random login errors

[Dimfacion]

Proposed changes

• Fixing random login errors

Related issues

• Login error after token expired #647

Checklist

• I consider the submitted work as finished
• I tested the code for its functionality
• I wrote test cases for the relevant uses case
• I added/update the relevant documentation (either on github or on notion)
• Where necessary I refactored code to improve the overall quality

Further comments

This needs to be tested extensively ... The fix is to prevent the callback of the SAML Provider to recreate an HttpSession if the previous one is older than 120s.
