Title: NEXUS-4985: AbstractGroupRepository#doRetrieveItem(ResourceStoreRequest) hides actual reason why something is not found in it's member

Changes:

* introduced "bookkeeping" for groups, made them not "swallow" member exceptions anymore
* REST API ?describe method changed to make use of this new information
* improvements for some exception messages
* improvements for some toString() methods (simply for easier debug)
