Update methods regarding the resource creation and the resource update at vo level.
In version 1.3 an error is given only if the update/create operation fails in the current VO. When a resource operation is performed, the new resource scopes are synchronized with the more recent one (matching the same id) found at vo level in the whole infrastructure. git-svn-id: http://svn.research-infrastructures.eu/public/d4science/gcube/branches/information-system/registry-publisher/1.3@181572 82a268e6-3cf1-43bd-a215-b396298e98cfrest-collector
