[10.x] use the same criteria StartSession uses on previous URL

[rodrigopedra]

Closes #46388

PR #46234 introduced a change on how the previous URL is calculated when the previous URL matches the current URL.

Unfortunately, it breaks redirecting back to the same URL, which is a common pattern on PATCH/PUT, as the previous implementation didn't consider which request method is being used.

• Changes the previous URL calculation to use the same criteria StartSession middleware uses to check if it should update the previous URL in session

I guess we could extract this logic to the request object. I wanted to propose a quick fix for the introduced error

[rodrigopedra]

Not sure why just one set of tests, failed, from the running time it seems it got stuck somewhere and ended up failing.

StyleCI cloudflare human verification keeps me on a verification loop, so I couldn't see what is wrong.

I had to revert the other PR and tag a patch, so I'm guessing this PR isn't complete anymore.

I'm also hesitant to keep chasing down this road.

@taylorotwell sorry for the inconvenience caused. This PR was more like a hot-fix attempt.

When I saw the related issue, I just wondered to share what I use, which doesn't break as I only use it at blade templates. I didn't think on the broad usage.

I guess it is better to close this by now, and then propose a more thoughtful solution, considering those other caveats. Perhaps closer to 11.x.
