Fix error on orphaned Edorg when rendering EdOrg Tree for app enable / authorization

edorg_tree_helper.rb raises an exception when there is an orphaned
edorg. This prevents anyone from enabling or authorizing apps in
Admin-Tools when such a situation occours. This fix logs an error to
the rails console, omits the orphaned edorg from the tree and displays
the missing edorgs below the tree.
Adding same report of orphaned edOrgs below edOrg tree for app enablement
html tag issue, nicer ruby code
