Re-enable ActionMenuPresenter view recycling

Since action bar transitions are turned off again for now, re-enabling
item view recycling fixes an unfortunate regression with submenus.

If a menu view is invalidated while a submenu is open we need to keep
its anchor consistent. With view recycling active we preserve status
quo and the previous anchor view instance for the popup window remains
in place.

In the future this will need to get more sophisticated;
ActionMenuPresenter will need to re-parent an open submenu against the
proper anchor view by menu item id. But that is a change for another
day.
