INCOMPATIBLE: Return {} for missing $!all-json
%$!all-json% will return a {}-wrapped object if there are are any events, or when there is an attached (empty) pMsg->event, but an empty string if nothing is attached. Let it return an empty object "{}" in that case for consistency. In particular, this allows $template MongoTemplate,"{%hostname:::jsonf:sys%, %$!all-json:2:$:%" to always result in a valid JSON.
