[BUG] Empty Deletion Reason Does Not Trigger Delete Webhook

[BellCubeDev]

Couldn't get that out of the team. Best I got was "presumably the latest". I know there's no billing tab in the admin panel so I do believe we're self-hosted.

Describe the bug
When deleting a suggestion without providing a reason, deletion webhooks aren't triggered.

To Reproduce

1. If no deletion event webhook exists, create one. Use the built-in test feature to ensure it works before continuing.
2. Create a dummy suggestion.
3. As an admin, enter the delete dialog.
4. Do not provide a delete reason.
5. Delete the suggestion.
6. Check your webhook destination. No webhook event should have been sent.

Expected behavior
A webhook event should be sent, even when no deletion reason has been provided. Without these events, knowing whether a suggestion has been removed from an external event log is inconsistent at best.
