Fixed Marking a Trade with no Sell -> Text displayed as "Sold to for "

Device: PC
Browser: Chrome
OS: Win10

Steps to reproduce:
Mark a Trade as SOLD, with no Seller
- Valid scenario as Traders can possibly sell item in game

Anything else to add:
Would love to see an option of SOLD IN GAME, or something along those lines, perhaps a Switch between that or diablo2.io member (which would bring up text input box)
- or text should say "Sold for..." when no Seller is inputed

This is yet to be updated with 'N/A' like it is in all other instances on the site so that people know it was sold, but the seller didn't bother to enter anything in the 'Sold to/for' entries.]

Won't be introducing a switch for 'sold in game', as the sold to section is fine for that, or they can just leave it blank.
