Support all ReflectionType types

[ahjdev]

Take a look at
ReflectionIntersectionType
ReflectionUnionType

and just change the getArguments method to a recursive method

Note that ReflectionIntersectionType might need to validate all types while ReflectionUnionType must match just one type.
Also I wonder what happens if we combine both like: (Test&Message) | (Test2&Message)
