QTableView: fix Ctrl+End behavior with disabled columns

Ctrl+End moves the visual index to the bottom left index. This does not
work correctly when the item in the bottom left is disabled. It should
be fixed with 7863be3115 but does not due
to a typo.
Fix the typo by using the newly calculated visualColumn instead the
initial column.
There are cases where the algorithm still does not work as expected when
there are more disabled items but fixing them would add a lot of
complexity with no (much) gain.
