[FIX] website_blog: redirect /blog/x/post/y simplify

Don't try to keep extra params and co. Keep it simple...

Else we should pop from request.params `blog` and `post` keys because
now they are converted as query param with the slug format:

/blog/name-1/post-1?blog=blog.blog(1,)&question=blog.post(1,)

closes odoo/odoo#156990
