Note, that this change potentially has some other effects in corner cases (like the changed test data that is rather sensible because `bar` in the example is not effectively projected out and can be called with nulls) Probably, we need to consider rewriting all other isSomeType methods in KotlinBuiltins, but now it seems to be a rather dangerous change #KT-16424 Fixed
