fix(ts3server): improve ts3 ip parsing

[GrillGuth]

For Teamspeak3-Servers: Only use the first IP specified within the ts3server.ini file. The IP string is cut off after the first appearance of a comma (IP seperator within ts3server.ini files).

Description

As described inte teamspeak server documentation the voice_ip parameter allows a comma separated IP list. Currently when e.g. "voice_ip=12.345.678.910, 1a23:b456:7891:011::1" is specified which is according to ts standards LinuxGSM will extract "12.345.678.910 1a23b45678910111" as IP string and can not deal with it. As a workaround till more then one IP and IPv6 is supported the IP string should be cut off after the first appearance of a comma.

Fixes #2658
