[FIX] website,website_hr_recruitment: fix crawler (job url)

Commit 2ab6ce80d6 introduced an issue where the
URL for new job offer was added in the DOM even when website_hr_recruitment is
not installed.

This is a problem because the crawler tries to navigate that URL and returns an
error because the route does not exist without website_hr_recruitment.
