Treat "users.php" and "profile.php" as the same parent menu. This fixes situations where it's impossible to hide a "Users" sub-menu item from roles that don't have access to the "Users" menu and instead get a "Profile" menu.

Caution: This is the kind of thing that can have unforeseen consequences.
