fix #12364 - History dialog: show old and new coordinate on map

[Klumbumbus]

This is a great feature!
I noticed that the zoom is not yet working corrctly in all cases.
r9441 from jenkins

What steps will reproduce the problem?

1. move existing node 1km
2. strg+H, coordinates tab
3. map is zoomed out far
4. select a different A B pair for comparison
5. select again the penultimate ‎and the last version for comparison
6. see, how the zoom is fine now
