This problem appeared when testing NDS-221.

Steps to reproduce:

• Login to UI
• Setup a Dataverse stack with optional DV iCAT service
• After confirming the configuration, expand your new stack and view the service list
• Click "Remove Service" next to Dataverse iRODS iCAT
• The service should be "removed" from the stack
• Click on the "Volumes" tab
• Even though we have deleted 1 of the 4 services requiring a volume, all 4 volumes remain "attached" to our stack
• Refresh page
• The DVICAT volume is detached
