Require action menu items registry at the top of uls interface module

"ext.uls.actions.menu.items.registry.js" should be required at the
top of the "ext.uls.interface.js" file. The latter is the main file
of the "ext.uls.interface" module, and it's the only one that is
executed when the module is added as an external dependency. Since,
the "mw.uls.ActionsMenuItemsRegistry" object is needed outside ULS
extension (inside ContentTranslation), the corresponding file should
be required at the top of the main file so that it's available.
