Subject: [PATCH] Fix keyboard navigation crash in single column generic
 wxDataViewCtrl

Selecting a leaf node in a wxDataViewCtrl and then pressing the right arrow
key resulted in using an out-of-bounds index for accessing the columns list.

Fix this by setting the current column to the first one, and not to the second
one which might not exist.

Closes #17537.
