Since 0f1008a593, views record if they
moved the item in the model, and prevent the deletion of the source item
in QAbstractItemView by setting the dropEventMoved private data member.
However, QListView in icon mode is special: it doesn't rearrange the
model, it repositions the icons in the view. While the dropEventMoved
logic was applied to the drag event filter to prevent deletion, the
variable was never set in the filterDropEvent handler. The drop event got
ignored, breaking rearranging of icons.
Fix this by setting the dropEventMoved member in filterDropEvent.
