> Possible NPE in LocalClient after TEZ-4236

> {code}
> the problem only affects LocalClient, so not a production-level issue, but
> unit tests can fail with this problem
> the original getAMStatus in FrameworkClient detected the non-readiness of the
> AM through the proxy:
> {code}
> if (proxy == null) {
> return TezAppMasterStatus.INITIALIZING;
> }
> GetAMStatusResponseProto response =
> proxy.getAMStatus(null, GetAMStatusRequestProto.newBuilder().build());
> return
> DagTypeConverters.convertTezAppMasterStatusFromProto(response.getStatus());
> {code}
> a similar solution should go to LocalClient, and only if
> isLocalWithoutNetwork is on
> {code}
> if (clientHandler == null){
> return TezAppMasterStatus.INITIALIZING;
> }
> return clientHandler.getTezAppMasterStatus();
> {code}
