Issue Summary

When a Service is deleted (Operations > Services), it'll remain linked to any work items previously using that Service.

This causes work items to be incorrectly visible in search results, for example, using "Affected services" IS / IS NOT EMPTY queries.

Steps to Reproduce

1. Create a new service (Operations > Services)
2. Create a new work item and link the Service (via Affected Services field) - i.e. ITSM-305
3. Delete the Service (Operations > Services)
4. Browse back to the work item and confirm the Service is no longer listed in the Affected Services field -   expected
5. Run the following JQL

   key = itsm-305 and "Affected services" IS NOT EMPTY

Expected Results

The issue is not listed in the search results

Actual Results

The issue is listed in the search results

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
