The situation actually was that the Wise thought one of the Nazgûl to be the Necromancer, and maybe that was indeed the intention of Sauron, who wanted time to rebuild, and such anonymity would have suited him well.

Good point. I suppose the real reason Sauron got the "Necromancer" was that wahtever was in charge in Dol Guldur was already assumed to be a necromancer, and
once it's true nature was revealed, the name had already stuck. And since it was not considered good to call Sauron Sauron, having a convenient alternate handle would likey have been considered a handy thing. Plus as long as there were Nazgul there as well (and there usually were) it is likey that there were necromancers within the walls (if one assumes all of the Nazgul are necromantically skilled, and the Witch king is simply the best at it.)
