When the view menu became available in the model, the topright was not
adjusted in StackRenderer. Fix to properly call the adjustTopRigth in
case children are added.
Furthermore, the view menu is not synchronized to the E4 model when
updateActionBars is called. Enabling this synchronization is too risky
now (RC1), therefor bypassing the model and renderers and forcing an UI
update of the topright.
