[SR-Users] bug in textops module

[Juha Heinanen]

according to textops readme:

2.1. Kamailio Modules

   The following modules must be loaded before this module:
     * sl -- Stateless replies.

however, i get these errors if pv module is not loaded before textops
module:

Mar 14 10:14:52 wheezy1 sip-proxy[4707]: ERROR: <core> [pvapi.c:790]: pv_parse_spec2(): error searching pvar "avp"

please fix textops module so that it does not depend on pv module if
rpid_avp is not set.
