oox smartart, org chart: handle multiple elements in hierChild

In case one manager has multiple employees, then we laid out only the
first one. Recognize non-assistant type as the node type (as a start) to
get the correct number of employees (when there are no assistants), and
also render employees on a horizontal (and not on a vertical) path.

With this, the 1 manager and multiple employees case looks reasonable.
