mod_bookmarks: Reduce error about not having bookmarks to debug (thanks tom) This is happens if the account is new and doesn't have any bookmarks yet, which is not a problem. Rarely seen since most clients currently use the older version of XEP-0084 stored in XEP-0049 rather than in PEP, but at least one (Converse.js )does. One scenario in which this would show up often is with Converse.js as a guest chat using anonymous authentication, where all "accounts" would always be new and not have any bookmarks. This scenario probably does not need to have mod_bookmarks at all, but if enabled globally it would likely become loaded onto the VirtualHost unless explicitly disabled.
