Attaching trivial patch that moves the call to updateVersionAndAnnounce at the
end of mergeSchema.
> Don't announce schema version until we've loaded the changes locally

>
> Currently, we call updateSchemaAndAnnounce (which sets the schema version in
> the system table and announce it on gossip) in DefsTable.mergeSchema as soon
> as we've persisted the schema mutation but *before* we've actually loaded
> new/updated KS/CF locally. This makes it impossible to reliably check for
> schema agreement in a cluster as even if all nodes have the same version set
> in the system tables, you could still get an insert on a new table rejected
> because the table hasn't been loaded yet.
