Fixed build problem with dev mode enabled, which was caused by commit 321100.  Reformulated patch to be more generic.

Moved the sip uri parse variable initalization to parse_uri_full in reqresp_parser.c.  This will ensure that any use of parse uri will have null output variables if the parse fails.

(closes issue #19346)
