Commit d3f4f5f208ee76a22ff39c13df4d150712685f5f introduced automatic conversion to FileInfo and DirectoryInfo but failed to properly handle the conversion if the value comes from the [DefaultValue] attribute.
Using both `var (converter, stringConstructor) = GetConverter(...)` and `var (converter, _) = GetConverter(...)` should have been a red flag!
