LUCENE-4953: Fixed ParallelCompositeReader to inform ReaderClosedListeners of
its synthetic subreaders. FieldCaches keyed on the atomic childs will be purged
earlier and FC insanity prevented. In addition, ParallelCompositeReader's
toString() was changed to better reflect the reader structure.
> readerClosedListener is not invoked for ParallelCompositeReader's leaves
