    treeview: Reset multipress controller after 2nd click
    
    The pre-gestures code used to compare the current button press with the
    previous one on !activate_on_single_click, and unset the previous event
    data so ::row-activated would be emitted every 2 clicks.
    
    So do the same with the multipress gesture and reset it after every 2nd
    click to have ::row-activated emitted multiple times while manic clicking.
