Mahmood Ali 37c6160b96 Handle nil/empty cluster metadata 
Handle case where a snapshot is made before cluster metadata is created.

This fixes a bug where a server may have empty cluster metadata if it
created and installed a Raft snapshot before a new cluster metadata ID is
generated.

This case is very unlikely to arise.  Most likely reason is when
upgrading from an old version slowly where servers may use snapshots
before all servers upgrade.  This happened for a user with a log line
like:

```
2020-05-21T15:21:56.996Z [ERROR] nomad.fsm: ClusterSetMetadata failed: error=""set cluster metadata failed: refusing to set new cluster id, previous: , new: <<redacted>
