schneuwlym created an issue (kamailio/kamailio#4173)
### Description
The output of `kamcmd dns.view` shows two times the parameter `rr_regexp`, but
`rr_replacement` is missing.
### Troubleshooting
#### Reproduction
Lookup a NAPTR record with `kamcmd dns.lookup NAPTR ...` and check the output
```
# kamcmd dns.lookup NAPTR test.example.com
{
name: test.example.com
type: NAPTR
size_bytes: 328
reference_counter: 2
permanent: no
expires: 300
last_used: 0
negative_entry: no
records: {
{
rr_idx: 0
rr_order: 10
rr_preference: 10
rr_flags: S
rr_service: SIPS+D2T
-> rr_regexp:
-> rr_regexp: _sips._tcp.test.example.com
rr_permanent: no
rr_expires: 300
}
{
rr_idx: 1
rr_order: 20
rr_preference: 10
rr_flags: S
rr_service: SIP+D2U
-> rr_regexp:
-> rr_regexp: _sip._udp.test.example.com
rr_permanent: no
rr_expires: 300
}
}
}
```
