It's simpler to look at sealedSubclasses directly than to determine isSealed, so I fixed it while I was at it.

findSubtypesis defined to returnnullif nothing can be retrieved.https://github.com/FasterXML/jackson-databind/blob/2644cba99ec5e23ffdbe85dfe00fb471e5aa0d9c/src/main/java/com/fasterxml/jackson/databind/AnnotationIntrospector.java#L483

sealed classmay not have any classes to inherit from.In this case, the conventional implementation of
findSubtypeswill return an empty List.So I modified it to return
nullin case of an empty list.Also, it is simpler to look at
sealedSubclassesdirectly than to determineisSealed, so I fixed it while I was at it.
