Does not initialize collections in records when overrides are used

[mjureczko]

Given

record MyRecod(
        String is,
        Set<String> strings,
        List<String> stringsWithOverride) {
}

When

var actual = some(MyRecord.class, Map.of("stringsWithOverride", ()->List.of(someString()));

Then actual.string is an empty set.
