[FIX] website_hr_recruitment: redirect deprecated /jobs routes

__Current behavior before commit:__
`/jobs` routes have been modified in [this commit][1]. Old ones are
deprecated but are still working for backward compatibility.

When searching on this page, search params are now just added at the end
of the URL (instead of being part of the path like before).
If the URL of the page is a deprecated one, this can create a conflict
with the previous way the params were handled and produce an error.

__Description of the fix:__
Redirect the user to the new route any time he tries to reach the
deprecated ones. Any parameters included in the old URL will be carried
over to the new route to maintain expected behavior. If a parameter is
provided both in the path and as a kwarg, the kwarg value will take
precedence.

__Steps to reproduce the issue on runbot:__
1. Go to `/jobs/country/20`
2. Make a search using the search bar -> Crash
