[syslog-ng] [PATCH 7/7] jsonparser: Only prepend a prefix if there is one

[Gergely Nagy]

In log_json_parser_process_single(), when parsing an object element,
only prepend a prefix if there is one, otherwise g_string_assign()
will complain on stderr with an assert, which is not something we'd
like.
