### Description

I was testing latest nightly build to test uacreg with auth_ha1 column. I have 1 record in database: ``` id: 1 l_uuid: 50b08f96-ee5d-44bb-8539-098268ad64d1 l_username: covalschi l_domain: test113.covalschi.reraldomain.com r_username: covalschi r_domain: sip.linphone.org realm: sip.linphone.org auth_username: covalschi auth_password: auth_ha1: f0e0dc4bf176fe8f41280b7b3758150d auth_proxy: sip.linphone.org expires: 3600 flags: 0 reg_delay: 0 socket: ``` When I execute kamcmd uac.reg_reload I get: ```ERROR: read reply failed: Success (0)``` as return code for kamcmd and Kamailio crashes.

<!-- Explain what you did, what you expected to happen, and what actually happened. -->

### Troubleshooting

It repeats every time, Kamailio crashes with signal 11

#### Reproduction

Basically do the same - create a record in database with auth_ha1 instead of password and try kamcmd uac.reg_reload <!-- If the issue can be reproduced, describe how it can be done. -->

#### 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.

#### Log Messages

<!-- Check the syslog file and if there are relevant log messages printed by Kamailio, add them next, or attach to issue, or provide a link to download them (e.g., to a pastebin site). -->
