Fix a bug where action bar menus were using the wrong context to
inflate stock views. This was causing them to use the action bar's
themed widget context instead of the current theme's specific action
bar items.
Note that action views in the menu will still be inflated using the
themed widget context. This can produce some weird side effects if
the action views use theme attributes relating to these action bar
item attributes.
