Qt misuse of Role_if()

The Qt paper doll highlights known blessed/uncursed/cursed items with
a color border.  It was trying to force obj->bknown for non-blinded
priest[ess] but passed the old role letter argument to Role_if()
instead of the monster number that's used these days.  It was also
potentially modifying an invent item in a way that's observable to
the player but not updating persistent inventory to show that.

Probably didn't matter though; I don't think the situation it checks
for can occur anymore.  On the off chance that it could, move the
check-and-set out of #if ENHANCED_PAPERDOLL so that same inventory
update would occur for ordinary paper doll even though that doesn't
care about displayed items' bless/curse state.
