New Pipeline: Numerous bug and crash fixes:

* Fix RemoteInputView crash by no longer clearing the row.  This was never done in the legacy pipeline, and the number of components in the system which apparently depend on this terrible beahavior seems to be all of them.
* Fix ConcurrentModificationException in GroupExpansionManagerImpl due to iterating over the expanded groups to remove them.
* Improve the ListDumper to also include the group's summary
* Fix the ENR.addChildAt NodeController method to actually use the index
* Expand the ensureRemovedFromTransientContainer() logic to apply to all expandable views, not just section headers.
