Fix UB (invalid enum value) in tst_QTreeView

Browse Source 
As reported by UBSan:

  tst_qtreeview.cpp:663:5: runtime error: load of value 4294967295, which is not a valid value for type 'DragDropMode'

Instead of abusing -1 to indicate to not set the dragDropMode,
use a separate boolean field in tha data.
