[Core] fix timeout redirect location

[ridz1208]

Brief summary of changes

The feature introduced in #9041 seems to be broken on 26. The changes I'm proposing are the hack that i'm temporarily using on CBIG but there might be a better way of doing it.

One cause of the bug might actually be another PR submitted by maxime and merged #9055. not sure if the changes in that PR broke the chnages in #9041

Below are a couple examples of the existing redirect for URLs

http://localhost:8083/user_accounts/edit_user/rida
<a href="/login?redirect=http%3A%2F%2Flocalhost%3A8083%2Fedit_user%2Frida">Try logging in</a>

http://localhost:8083/configuration/
<a href="/login?redirect=http%3A%2F%2Flocalhost%3A8083">Try logging in</a>

@maximemulder @driusan I'd appreciate a quick look at this one

@kongtiaowang not sure why the tests are failing here, is the branch broken ?

[maximemulder]

@ridz1208 A GitHub update broke CI during the new year, the fix has been committed to main but not 26, so the branch is indeed broken. @kongtiaowang can you push the fix to 26 as well ?

[maximemulder]

#9055 got merged before #9041, so it did not break #9041 (in fact, it was a prerequisite to #9041).

I must say I am not sure why the current code does not work for you. I am not opposed to a fix but I'd prefer someone else to look into it if possible.

@maximemulder I agree someone else should look into it but on your end can you just see, on 26, the redirect works for you? I just want to know if its still working on your environment but not on mine

[kongtiaowang]

@ridz1208 @maximemulder #9536 will fix the CI failure issue.

@kongtiaowang I think this PR was assigned to you for testing.

Best way I found to test it is to login, go to a page with a complex URL, copy the URL, logout, try to go to the URL again (as if you timed out), you get a 403 error, then choose the option to try signing in and see if it redirects you to your original URL
