Fix legacy 64 player serverinfo, don't send duplicate packets (fixes #2495)

Browse source 
For legacy we sent the first packet once correctly, then the 2nd and 3rd
packet without the marker and token at the start, so they never worked.

For new 64 player serverinfo we sent all packets correctly but the 1st
packet twice.

Introduced in #1955.
