15906	[Patch] Isn't properly reverting multiple changesets	naoliv	team	"Have this object as an example https://www.openstreetmap.org/way/560417360/history
It was inserted in changeset 56253775 and deleted in 56254562.

If I ask to revert both changesets `56253775 56254562` I would expect this object to remain deleted.
ie, by first reverting `56254562`, JOSM would restore it; then by reverting `56253775`, JOSM should delete it.
In the end, for this specific object, nothing should be changed (since restoring + deleting = its current deleted status)

But the result is very different from this: JOSM just restores the object (and if we upload, we will reinsert it).

The test is very simple here: ask to revert both `56253775 56254562` and see the how object with `id:560417360` stays restored.
