PHPSemVerChecker\Comparator\Type::get does not support PhpParser\Node\UnionType

[danmooney2]

PHPSemVerChecker\Comparator\Type::get method does not check for instanceof PhpParser\Node\UnionType. toString method is not present on PhpParser\Node\UnionType or any other ComplexType, hence why a change was made here to specifically support NullableType. This should be updated to support all complex types introduced by PhpParser.
