Forwarded Prepare/Commit executed after transaction finished

Replicated TX cache, nodes A, B, C

0. A and B have topology 2, C already got topology 3
1. A sends prepare with topology 2 to B and C, both apply the prepare and respond
2. C forwards prepare to B with topology 3
3. A sends commit with topology 2 to B and C, both commit and respond
4. again, C forwards prepare to B with topology 3
5. A and B get updated topology id
6. A executes another transaction on the same entry
7. prepare and commit from first transaction with topology 3 arrive at B - B overwrites (or removes) the entry again

Result: on B we have inconsistent state
