Bad behaviour with currentIndex when changing the pathview model

There is a problem when the model of the pathview is loaded and you want to start always from the index 0 of the new model.

Steps:

1) Start testPathViewCurrentIndex.qml (attached with this report):

• The model isn`t loaded fine beause of QTBUG-18629

2) Press Key Left or Key Right in order to get a stable state of the view
3) Go to the index 5 (for example)
4) Press key Up or Key Down for changing the model

• Here you can check that the new model loaded is shown as it was in index 5
  5) Press key Right
• The view moves the path view from index=5 to index=1
