Data about all processes instances is shown at process instance list. But if we stop one of the running Kie containers, then data from the stopped Kie container are not displayed. And if we stop all remaining containers, then we can found, that data from all containers are displayed.
This data shouldn't be depend on the Kie container status and we should be able to see data from stopped and running containers.

Steps to reproduce;

Start kie workbench with Kie Server
Start 2 Kie containers on Kie Server
Start and complete processes from both containers
Check that Process Instance List has data from both running containers are displayed
Stop first container
Check that Process Instances List again - data from one running container are displayed
Stop second container
Check Process instance list - data from both stopped containers are displayed
