[FIX] website_blog: prevent helpdesk module to mess with blog perf tour

Commit [1] was introduced to fix an issue where the website menu cache
is incompatible with having a slug url in one of its menu.

But in the enterprise build, since the website_helpdesk module is adding
one menu containing a slug url, it would disable the menu cache.
Unfortunately, the website_blog perf tests (at_install) are executed
after website_helpdesk is installed, meaning that in enterprise, the
perf test of website_blog would fail since it would require some more
SQL Queries (1 or 2 depending of the test) to render a blog post as it
would have to query the website.menu table.

It's still unclear how commit [1] was merged in the codebase since the
enterprise staging should have failed.
