TreeView: Track model indexes during selection
As we keep track of the previous user-selected row,
it can happen that that row is no longer part of the
TreeModelAdaptor items if the user collapses it or
any of its ancestors (collapsing a node doesn't update
the current selection). This will result on the row
index pointing to the wrong entry in the model (or a
completely invalid one).
Instead, we now track the selection with QModelIndexes
making it more robust to branch expansion and collapse
in the view. We'll still need to account for model changes
which means that, in the future, we should invalidate
the previous user-selected item.
