### Description

I have list of dispatchers in `db_text`. But only first is processed.

#### Reproduction

Create `dispatcher` table in a case of db_text ``` id(int,auto) setid(int) destination(string) flags(int) priority(int) attrs(string) description(string) 2:1:sip:asterisk_2:5060:2:0::asterisk_2 1:1:sip:asterisk_1:5060:2:0::asterisk_1 ``` Start Kamailio

Run `kamctl dispatcher dump`

``` # kamctl dispatcher dump { "jsonrpc": "2.0", "result": { "NRSETS": 1, "RECORDS": [{ "SET": { "ID": 1, "TARGETS": [{ "DEST": { "URI": "sip:asterisk_2:5060", "FLAGS": "AP", "PRIORITY": 0 } }] } }] }, "id": 124 } ``` Only the first entry is processed.

On running ``` # kamctl dispatcher reload ``` nothing is changed.

### Possible Solutions

Adding other dispatchers via `kamcmd`
