Fix some focus traversal issues: * When we're on the only focusable view, AdvanceFocus() should just focus us again. * When only one focusable view exists, FindLastFocusableView() should return it, not NULL.  Also the code here was longer than it needed to be. Review URL: http://codereview.chromium.org/20347
