Fix some issues with Shift-selection in QAbstractItemView

This commit fixes some issues which occur when pressing the Shift key
while selecting items (new unit tests included):
1. The offset of the visible area is missing at one point in
QAbstractItemView::keyPressEvent, causing Shift-Arrow selection to fail
if the view is scrolled down.
2. Shift-click and Shift-Arrow selection fail after a rubberband
selection because d->pressedPosition does not correspond to a valid
QModelIndex.

The problems have been found in Dolphin:
