Subject: [PATCH] Clear Undo list when renaming

Our undo/redo list is tied to the screen that gets cleared when we
reload the file after renaming.  We need to clear the Undo list at this
point to prevent possible crashes when moving too far back in the stack

Fixes https://gitlab.com/kicad/code/kicad/issues/10504
