hostile djinni from potion

hostile djinni from potion

     Fix the situation <Someone> reported where the "You disturbed me, fool!"
result when releasing a djinni from a cloudy potion sometimes produced a
peaceful djinni for neutrals due to the usual randomness in how monsters
react to characters of the same alignment.  Explicitly force it to be
hostile for that outcome.

     Also, for the "it's about time" result, suppress the "It vanishes"
message when the character doesn't see the djinni depart.
