[bugfix] After adding product to cart toggle the cart drawer

[sirugh]

Description

When we moved updateItem to gql we, for configurable items, used the remove/add actions internally.

The add action used to invoke toggleDrawer('cart'), which no longer makes sense in this sense.

So instead of toggling within the action we now toggle in the UI where we should, after the action resolves.

Closes PWA-253.

2. Add a simple item to the cart. It should toggle the cart.
3. Update the configurable item. It should not close the cart after it is updated.
