Fix crash in wxListbook if image list is assigned after adding pages.

The generic wxListCtrl didn't properly support switching between report and
non-report modes without invalidating the control contents, the required in
non report view geometry info pointers were not allocated when the control was
switched to a, say, list mode and not created in it.

Fix this by updating all list control lines when the report mode changes.

Closes #11698.
