Browsing the menu data as super-user is not correct
because when we load the children menu the ORM
recursively calls menu.search(), this time as
admin, hence the groups of the admin are applied
or submenus, instead of the groups of the user.
The patch was also un-necessary, so there is no
reason to keep it.
