fix #H2797 - avoid "vision clears" if hero can't see

From 8 years ago, sitting on a throne and getting the confers-see-
invisible result gave "your vision becomes clear" message even when
hero was blind (who stays blind at the time).  Give an alternate
message if hero is blind, with another alternate when the blindless
is due to being poly'd into something without eyes.
