KT-53146 Don't coerce Nothing? returned from "catch" clauses

At first, I tried to modify the logic in PromisedValue.materializeAt
to get rid of all casts from Nothing? to other types, but that broke
a number of tests containing casts of java.lang.Void to other types,
so I decided to fix only this particular case with try...catch
(for some reason, here we get a null of type java.lang.Object).
