[FIX] web: history back from home menu

Since PR odoo/odoo/pull/124068, the browser history back no longer works
correctly when navigating from the home menu to applications. It requires
two history backs instead of one.

Why:
Two pushStates are performed on the router, the first to add the menu_id
and the second to apply the action associated with the menu.
These two pushStates are not in the same setTimeout, which causes two
changes to the url. So two entries in the browser history .

Solution:
We perform the two pushStates in the same setTimeout. This causes
only one url modification and therefore one entry in the browser history.

How to reproduce:
- Go to the home menu
- Click on the app A
- Return to the home menu using the toggle menu
- Click on the app B
- Perform a history back
- The home menu is displayed
- Perform a history back

Before this commit:
    The home menu is still displayed

After this commit:
    The app A is displayed.
