### Description
When using dispatcher module to select destination we didn't configure explicit port:
```
sh-4.1# cat /etc/kamailio/dispatcher.list
# $Id$
# dispatcher destination sets
#
# line format
# setit(int) destination(sip uri) flags(int,opt) priority(int,opt) attributes(str,opt)
1 sip:127.0.0.1 0 0
```
When we try to rewrite port in R-URI as in following configuration:
```
sh-4.1# cat /etc/kamailio/kamailio.cfg
#!KAMAILIO
#
debug=3
sip_warning=yes
port=5060
mpath="/usr/lib64/kamailio/modules/"
loadmodule "pv.so"
loadmodule "xlog.so"
loadmodule "dispatcher.so"
modparam("dispatcher", "list_file", "/etc/kamailio/dispatcher.list")
route {
ds_select_dst("1", "4");
xlog("will update <$ru>");
xlog("changing $rd to $dd\n");
$rd = $dd;
xlog("changing $rp to $dp\n");
$rp = $dp;
xlog("final RURI is <$ru>");
exit;
}
```
Kamailio crashes on line:
```
$rp = $dp;
```
Interesting thing is that we get port on previous line (see attached log).
### Troubleshooting
#### Reproduction
Use provided configuration and dispatcher.list file and send any SIP request message to Kamailio.
#### 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

list
If you are familiar with gdb, feel free to attach more of what you consider to
be relevant.

#### SIP Traffic
<!--
If the issue is exposed by processing specific SIP messages, grab them with ngrep or save in a pcap file, then add them next, or attach to issue, or provide a link to download them (e.g., to a pastebin site).

### Possible Solutions
<!--
If you found a solution or workaround for the issue, describe it. Ideally, provide a pull request with a fix.
-->
As a workaround all dispatcher module entries need to have explicit port configured.
