[FIX] web: fix menus and user language mismatch

[lade-odoo]

Steps to reproduce the issue:

• Have 2 different authenticated browser (one as admin and one as demo)
• With the demo browser, change your own language to French -> Reload the main menu page
• With the admin browser, update the demo user language from the Settings to English
• Reload the page on the demo browser, the menus will have stayed in French while the rest of the page is translated in English

Details:

• Only the first query after the following step will have an issue, the problem corrects itself on the second refresh.
• Could not reproduce on the runbot but could do it locally and on Odoo.SH (in 16.0) and on odoo.com free database (18.0).

This issue was already discussed more than a year ago (https://github.com/odoo/odoo/pull/110207) but was finally closed without being merged. The problem can now be fully reproduced while previously, it was a bit blurry.
