game: fix Classic 1.12 packed GUID for SMSG_PARTY_MEMBER_STATS

Browse source 
Classic/Vanilla uses ObjectGuid::WriteAsPacked() for party member stats
packets (same packed format as WotLK), not full uint64 as TBC does.
Reading 8 fixed bytes for the GUID over-read the packed GUID field,
misaligning updateFlags and all subsequent stat fields, breaking party
frame HP/mana display in Classic.
