Improve the audit logs for the action "Delete Issue Link"

Issue

Currently, the audit logs are using the Jira issue ID and issue link ID instead of the Jira issue Key to show the issues from which the link was deleted.

For example:

10103: blocks(10203)

It makes it very hard to understand which link was deleted, especially since we always show the issue keys for any other action in the audit log.

Suggestion

Make the message in the audit logs cleared by specifying the issue keys instead of the issue IDs.
