js error: Cannot read properties of null (reading time)

Added patch with the fix

The patch was not applying, but instead of re-rolling added the code to issue fork for easier maintaining. The code works, so in my POV can be merged, but will leave it to needs review. Tests are expected to fail for migrations 🌱 [META] Serialization issues in Migration tests Active .

The fix works but will need work when 🐛 Autologout triggered in background tab, no indication in other open tabs Fixed gets merged. So I'll postpone it for now.

Rebased the issue everything was rebased without an issue. Setting it to needs review.

Added a simple test that simulates having more then two responses from autologout ajax, by adding it in first place in array, so hard coding keys is not an option. The code in js file works as expected by checking the correct key and based on that sets the response. Leaving it as needs review so somebody can check the test added.
The testing is done via GitLab CI. To not cause confusion, hiding the patch file (which is applied in the issue fork).

Tests are passing here and locally, also testing by hand also worked fine. Setting this as RTBC.

Automatically closed - issue fixed for 2 weeks with no activity.
