RFR: 8200145: Conditional expression mistakenly treated as standalone [v2]

[Guoxiong Li]

> Hi all,
> 
> If the argument `Type t` of the method `Types.unboxedType` is an `ErrorType`, the `Types.unboxedType` may return the wrong result. And in this case, `Attr.isBooleanOrNumeric` and `Attr.isBooleanOrNumeric` return the wrong result, too.
> 
> This patch fixes it and adds a test case.
> Thank you for taking the time to review.

> Best Regards.
