Auto-renamed tickets no longer include the member's name by default

With Rename tickets to match their topic on, Wallu now names a ticket after its topic only, e.g. vote-rewards-missing. Servers that already had renaming turned on keep naming tickets the way they did. Want the member's name in it? Add {member_name} to the rename instructions in Ticket System in settings, e.g. Start the name with {member_name} - more on placeholders.
