Currently, when the topology coordinator accepts a node, it moves it to bootstrap state and assigns tokens to it (either new ones during bootstrap, or the replaced node's tokens). Only then it contacts the joining node to tell it about the decision and let it perform a read barrier.
However, this means that the tokens are inserted too early. After inserting the tokens the cluster is free to route write requests to it, but it might not have learned about all of the schema yet.
Fix the issue by inserting the tokens later, after completing the join node response RPC which forces the receiving node to perform a read barrier.
