Remove the proper widget during HildonTouchSelector column removal
Remove the proper widget during HildonTouchSelector column removal

Prior to the introduction of the HildonLiveSearch widget to
HildonTouchSelector, removal of a column implied a HildonPannableArea,
contained in HildonTouchSelector's hbox, to be removed. Now that there
is a vbox containing both the pannable area and the live search entry,
this vbox is the widget to remove instead.

Fixes: NB#149039 (controlpanel crashing in a scenario)
