Unsupported ast node functionType when function type used as generic type

[vchernyshov]

Hi, I have faced with java.lang.IllegalStateException: found errors: [found unsupported ast node ... in typeProjection! when was parsing Kotlin file that contains function type at generic type: List<(PricingPlan) -> Boolean>. According to source code only KlassIdentifier or KlassModifier allowed but in case of functionType the right will be DefaultAstNode.
