81e298a51d fixed a case where the focus
chain was screwed up when the order was already correct. This worked
correctly in most cases but not when the next focus widget of the first
one had Qt::NoFocus.
The optimization check if lastFocusChildOfFirst is the same as second is
thrown away since it now does not longer screw up the focus chain and
the save would only be four pointer assignments.
