oox smartart, vertical bracket list: fix node counter condition

The visible effect of this was that the 2nd level text nodes were
missing from the layout result.

The cause is that when it comes to counting nodes of a condition, we
assumed that the current layout node is a presentation of a model node,
but this is not necessarily true.

Fix the problem doing a "first presentation child of", then a "presentation
of" navigation in that case, which leads us to the correct model node,
so counting its children works.

(An alternative way of getting non-zero children would be a
"presentation parent of" navigation, followed by a "presentation of"
navigation, but that would lead us to the document root, so we would
count the number of 1st level elements, not the correct 2nd level
elements.)
