[Freeciv-Dev] (PR#10026) bad behavior with cityrep's "add first"

["Jason Short" <jdorje@xxxxxxxxxxxxxxxxxxxxx>]

I kept finding my worklists really long and full of useless items I 
didn't remember adding.

It turns out if you "add first" an item, and that city can't build that 
item (like adding a marketplace to a city with a marketplace) it instead 
duplicates the current item.

Of course you can't add a marketplace to a group of selected cities 
unless at least one of those cities can build the marketplace.

This is with the effects patch, but I doubt this makes a difference.
