[FIX] website, test_website: clear menu cache correctly

[This commit] fixed an issue with the menu cache. Unfortunately, during
the forward port, we missed updating the cache key according to what has
been done in [this other commit]. This commit updates the cache key and
improves the test.

Steps to reproduce the bug fixed by this commit:
- Render a website without a record URL in the menu (to the cache)
- Edit the website's menu
- Add a link to a product page (e.g., customizable-desk)
- Add a link to another product (e.g., chair-floor-protection)
- Save the menu
- Click on the menu link to go to customizable-desk
=> At this point, the active menu element is correct
- Click on the menu link to go to chair-floor-protection
=> The active menu element does not update

This issue does not occur if there is a record like URL in the menu
before the first render.
