### Description
<!--
Explain what you did, what you expected to happen, and what actually happened.
-->
Segmentation fault when sip_trace method is called with less then 2 arguments.
### Troubleshooting
The problem does not happen if either "xheaders_write" module param is set to zero or we provide both arguments to sip_trace method.
#### Reproduction
<!--
If the issue can be reproduced, describe how it can be done.
-->
<pre>
..
# ----- siptrace params -----
modparam("siptrace", "trace_on", 1)
modparam("siptrace", "hep_mode_on", 0)
modparam("siptrace", "xheaders_write", 1)
modparam("siptrace", "trace_to_database", 0)
modparam("siptrace", "trace_flag", FLT_SIP_TRACE)
modparam("siptrace", "traced_user_avp", "$avp(traced_user)")
modparam("siptrace", "duplicate_uri", "WEBRTC_SIP_TRACE_ADDRESS")`
..
request_route {
..
  sip_trace("WEBRTC_SIP_TRACE_ADDRESS");
  setflag(FLT_SIP_TRACE);
..
}
..
</pre>
#### Debugging Data
<!--
If you got a core dump, use gdb to extract troubleshooting data - full backtrace,
local variables and the list of the code at the issue location.
gdb /path/to/kamailio /path/to/corefile
  bt full
  info locals
  list
If you are familiar with gdb, feel free to attach more of what you consider to
be relevant.
