Issue Summary

When the default event fired by the "Fire event Function" post function is changed in a workflow transition to a different system event, a related webhook is not fired, or an incorrect webhook is fired, depending on the chosen event.

This doesn't affect custom events, as they were fixed in JRACLOUD-76673.

Steps to Reproduce

1. Edit the 'Fire Event Function' post function to fire a different system event than the default

Expected Results

• for the initial transition - the jira:issue_created webhook is being sent
• for any other transition - jira:issue_updated webhook is being sent

Actual Results

Webhooks are not sent at all, or Jira sends incorrect webhooks.

Workaround

Restore the default event in the "Fire event Function" post function:

• Create Issue for the initial transition
• Generic Event for any other transition
