mod_bookmarks: Fix traceback on attempt to convert invalid bookmark
Found by accidentally publishing {urn:xmpp:bookmarks:0}conference
instead of :1 due to testing this earlier for the blocking.
By the principle of garbage in, garbage out, just generate a bookmark
from the item id / JID and carry on with a warning.
