When ambiguous classes are in a list / array they are given their simple name not FQCN

When determining if an instance of a parameter needs a simple name or a FQCN, the JENKINS-43337 fix uses the erased type of the parameter which will fail for the cases where the parameter is a container parameter such as a List or Array, instead the erased type of the container's generic parameter should be used as there will be no instances of type `List` or `[]` so the simple name will be used always
