Bug Report: Username Cleared When Editing Confirmed Ticket Without Login

Steps to Reproduce:

1. In WordPress admin, navigate to wp-admin → Tickets → Attendees and filter Published tickets.
2. Select a confirmed ticket that has a username attached.
3. Copy the unique edit URL for that ticket.
4. Open a new incognito window or log out of the website.
5. Paste the edit URL in the browser and attempt to modify the ticket.
6. Save the changes.

Expected Behavior:

• The username associated with the confirmed ticket should not be cleared.

Actual Behavior:

• The username field gets cleared after editing the ticket while not being logged in.

Additional Context:

• A previous fix restricted unconfirmed tickets from being edited without logging in.
• However, confirmed tickets are now affected when edited via the unique URL without authentication.

Priority: Medium (Affects data integrity for confirmed tickets)

Suggested Fix:

• Ensure that the username is preserved when editing confirmed tickets, even if the user is not logged in.
• Validate the ticket edit process to maintain username data integrity.

I think I can see the problem here - will work on a fix.

Essentially, the username gets updated with a blank user, so isn't set.

@pkevan I saw you updated production branch. I tested it on live WordCamp website of Kolhapur with 2 conditions below. Fix works well properly.

• Edited ticket without login
• Logged in as site admin & edited ticket

Ticket do not lose username.
