How to update peer's blockstore when the whole topology changed

[mversic]

I wounder how we should deal with more general case when whole topology changed.

Step by step:

1. Network is started with peer set A
2. After some height peer set A is replaced with peer set B (A intersection B = empty set)
3. New peer is added with trusted peers peers from set B
4. Peer get block and update it's topology to set A (because at this height only peers from topology A were present)
