> When we are doing a CAS operation we need to figure out what protocol is
> used, and if the table isn’t known to TCM we fall back to paxos. This
> happens when you call local system tables as they are not in TCM, but the
> return was missed so we try to infer the protocol from the null TableMetadata
> and fail with a NPE
