On internal shares the controller is called without the share token. But necessary information, like share attributes, might be necessary to know and are available from the super share of the SharedStorage in that case. For this approach was used elsewhere, too, some repetitive code was consolidated in the Helper class. Signed-off-by: Arthur Schiwon <blizzz@arthur-schiwon.de>
