Previous scene shouldn't depend on the action that follows it. Having looked at a few examples I think the call the get_carousel_state isn't needed.

SearchFurniture and NavigateCarousel actions result in views
of the carousel so don't need to include any previous in-focus
items. These are implicity removed by these two actions.

Making the "before" scenes more stable.

Screenshot fix

Leave out focus item when action is Search or Navigate

Raw actions are split by messages, not necissarily by when sharing
occurs. This is especially noticible when, say, a SpecifyInfo action is
inserted which doesn't often align with a share actions. Thus need to
take into acount when 'Share' occurs to determine the final scene as seen
by the user as the result of an one round.

Setting turn_carousel_state based on 'Share'
