Title: uix:ActionBar make items added to ActionOverflow persistant in the overflow dropdown. Minor bug fixes.

- Support keeping items in overflow icon always if items are directly added to ActionOverFlow
- Fix positioning of items when they are re-added to the Actionbar using `group_index` to calculate the
position to insert the items.
