This directive anyway does not make test run twice with OI, and with NI
It only once run the test with specific settings (// LANGUAGE)
and ignores irrelevant (OI or NI tags)
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
