Fix #35275 (PART2) - TR104: Support multiple SIP accounts

When applying asterisk server URI, asterisk.sip_service_provider.host
should take precedence over asterisk.sip_service_provider.domain.

TR104 parameters ...SIP.Network.RegistrarServer and .ProxyServer
are all mapped to UCI asterisk.sip_service_provider.host.
