protocol: don't drop a connection if we can't get a compatible chain

Browse Source 
This can now happen if:
- we have a pruned db
- we have not connected to the monero network for a while
- we connect to a node
- that node asks us for history
- we only have a pruned version of the most recent common block

In that case, it's better to not reply but keep the connection alive,
so we can sync off it.
