[xdc] Workers connected to standby cluster not picking up tasks after failover

Expected Behavior

Workers connected to standby cluster should start picking up tasks when proted as teh active cluster

Actual Behavior

No taks get dispatched to the worker connected to standby cluster

Steps to Reproduce the Problem

1. Create an xdc setup in docker compose bring up the cluster using
   docker compose -f docker-compose-mysql-xdc.yaml up
2. create a global namespace named xdc with clusters active and standby
3. create some workflow in xdc namespace
4. bring down the active cluster (i.e temporal-active, temporal-active-admin-tools, temporal-active-web) (kill specific containers)
5. log on to temporal-standby-admin-tools and fail over to standby cluser using tctl -ns xdc n u --ac standby

The workers (java sdk) connected to the standby cluster is still not getting any workflows/tasks dispatched.

this behaviour is with java sdk based worker/clients
