Don't create Menu UIX components without an id

In XWiki 9.8RC1 Thomas added some warning to discover when some UIX component are created with without an id and to log a warning when that's the case. This made us discover that the Menu app does this and it looks like hack that would need fixing (Note that FTM we removed the warning, see XWIKI-14707).

Also note that we need a proper way to disable a UIX component, see XWIKI-13076
