Subject: [PATCH] Use getName() if available

ReflectionType::__toString() has been deprecated in favor of
ReflectionNamedType::getName(). The documentation states that this:
> As of PHP 7.1.0, ReflectionType::__toString() is deprecated, and
> ReflectionParamater::getType() *may* return an instance of
> ReflectionNamedType. To get the name of the parameter type,
> ReflectionNamedType() is available in this case.

Since this implies there is no guarantee to have a ReflectionNamedType,
I added a type check, falling back to the use of the deprecated API.
