## Problem
* Fixes LKB-743
We get regular assertion failures on staging caused by a race with chaos
injector. If chaos injector decides to migrate a tenant shard between
the background optimisation planning and applying optimisations then we
attempt to migrate and already migrated shard and hit an assertion
failure.
## Summary of changes
@VladLazar fixed a variant of this issue by
adding`validate_optimization` recently, however it didn't validate the
specific property this other assertion requires. Fix is just to update
it to cover all the expected properties.
