fix #U782 - undead turning in a shop [trunk only]

Reported last December by <email deleted>.  Using
a wand or spell of undead turning inside a shop used up corpses without
checking whether they were owned by the shop.  Although the report didn't
mention it, using stone-to-flesh on statues had the same problem.

     I'm not completely satisfied by some aspects of this code, but if I
don't commit what I've got now I probably never would.  My original notes
are lost; I thought that there were some additional fixes present, but
looking at these diffs I don't see anything else significant enough to
warrant mention in the fixes file.
