(svn r3319) - Fix (regression): "Unnamed Competitors". A result of revision r3224 which allowed AI's for multiplayer. Old AI's didn't function correctly anymore. The update of last-built tile is moved back, but to a slightly different place so it is only executed when the command is actually successfully executed. This code shouldn't be neccessary, but alas, the old AI doesn't use DoCommandDP() functions.
