    collection-view: Hide items until wizard is finished
    
    In case of local VMs, we create the machine already before user is out
    of wizard. However, we don't want this newly added machine to be visible
    until user has hit 'Create' button and/or is out of wizard state.
    
    This patch defers the addition of new items to collection view until we
    are out of wizard state.
