HintedHandoff fails with could not reach schema agreement

To reproduce, have two nodes A and B.

1. On node A, create a keyspace with replication factor 1 and add a column family
2. Ensure node B has created the keyspace and column family
3. Take down node B
4. Insert some keys to A at CL.ANY, ensuring some keys should be written to B
5. Bring up node B
6. When hints are delivered, I get the error:

If I use DatabaseDescriptor.getDefsVersion() instead of gossiper.getEndpointStateForEndpoint(FBUtilities.getLocalAddress()).getApplicationState(ApplicationState.SCHEMA) then the error goes away, and the hints are correctly delivered.

This may be the same issue as Aaron saw here: http://cassandra-user-incubator-apache-org.3065146.n2.nabble.com/ApplicationState-Schema-has-drifted-from-DatabaseDescriptor-td6006576.html, and may be related to CASSANDRA-2083.
